crash possibly due to bad symbol lookup

I have a c++ app running on OS/X Lion which crashes in a call to glIsBuffer(0). The XCode 4.5 stack trace states:

error: address doesn't contain a section that points to a section in a object file

and DYLD_PRINT_APIS shows:

dlopen(/System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/CoreGraphics,0x00000009)...

dlsym(0x7f9288d00cd0, gliCopyAttributes)

dlsym(0x7f9288d00cd0, gliGetVersion) dlsym(0x7f9298d70620, __CGBitmapContextDelegateCreate)

dlsym(0xffffffffffffffff,CGSCopyCoreGraphicsCapabilities)

Segmentation fault:11

The last call to dlsym() appears to have been passed a rather strange library handle. I looked at the return values for dlopen, but it should be returning NULL on error. There are no errors reported for the dlopen calls in the log.

CGSCopyCoreGraphicsCapabilities is a Core Graphics call, though Google doesn't turn up any docs on it. My current hypothesis is that dlsym is using an invalid library handle. Perhaps the proper Core Graphics library is not loaded or has been unloaded.

Running otool shows a few version mismatches:

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)

/usr/lib/libstdc++.6.dylib(compatibility version 7.0.0, current version 52.0.0)

but I don't know enough to say whether they are relevant.

Can anyone help to decipher what might be the problem?

thanks!

ok.. it's not crashing directly in the source code based on the stack, though. In XCode 4.5 debugger:


Thread 1

com.apple.main-thread

0 0x00000000

1 BufferObject::clear()


where the source is:


void

BufferObject::clear()

{

if (glIsBuffer(mIndexBuffer) == GL_TRUE) // << crash occurs in call to glIsBuffer

...

Thread 1

com.apple.main-thread

0 0x00000000

1 BufferObject::clear()

but, thread 0 is the one that's crashing somewhere in the boost library....


What's at?

8 vdb_view 0x000000010e976428 main + 3032


This is probably the culprit:

7 vdb_view 0x000000010eadad7b Viewer::view(std::vector<boost::shared_ptr<openvdb::v0_103_1::GridBase const>, std::allocator<boost::shared_ptr<openvdb::v0_103_1::GridBase const> > > const&, int, int) + 331

What do you mean by a "c++ app"? This is written in c++, has a main(), is built by a makefile, and probably does not resent being called a "c++ app".


I suspect this might be something to do with the way the components are linked together at runtime, perhaps two incompatible components coming from different paths.


dlsym(0xffffffffffffffff,CGSCopyCoreGraphicsCapabilities)


might be a good place to start. Does anyone know whether this is normal? If not, some information on what might cause this would be nice.

ah.. your post hadn't arrived while i was composing mine.


Thread 1 in Xcode == Thread 0 in the Problem Report.


I'm not sure how you are determining that there is a crash in the Boost library. The stack shows that control passes through calls 7 and 8 on the thread, eventually ending up calling glIsBuffer() so I guessed you were thinking a memory issue might be involved.


So i ran it through valgrind and there many complaints about glfw and Core Graphics using uninitialized values so I suspect it's a porting issue. Could take a while. I'll skip around this one for now as there is an alternative GUI.


thanks for your help!

I was making a reference to your initial categorization of your program as "a c++ app". It isn't. It is an OpenGL application written in C++, using Boost, glfw, vdb_view, valgrind, and who knows what else.


For this app, you asked for assistance in an Apple Development forum. That probably wasn't the best approach. Your app is only superficially a Mac app. You appear to have resolved the problem on your own. In the future, if you are working with specific open-source libraries using their build scripts, it would probably be best to go to the authors of those libraries first. It isn't that your questions aren't welcome here, it is just that you aren't likely to find a speedy answer here.

Jan 19, 2013 7:03 PM in response to wrabbit99

They are around but those are very specific technologies. I am not going to install and test something on that order of difficulty. If it was something I already knew or something I thought might be interesting to learn, then I would might go for it.


It isn't that OS X has BSD roots, but that it is wearing a BSD wig. It is a compatibility layer. There is not a strong connection between the BSD/Linux community and the Mac world. These cross-platform, open-source libraries are particularly difficult. They often have hacks to run on one specific version of OS X and those hacks are rarely updated. That can be a problem on OS X because Apple doesn't shy away from breaking old code.

Jan 19, 2013 8:58 PM in response to etresoft

The rest of my codebase is already on Mac so I didn't take my normal course and run it on Centos. Danger is my middle name :>).


I inherently object to the notion of BSD as a "wig" but for now I will take your word for it :>). There are going to be a large number of interesting open source projects in the next decade, many of them from new and large markets, so IMHO Apple should take care to allow these projects to port easily or those developers will not be exposed to the OS - and developer mindshare, as you know, is very difficult to get back once you have lost it. Anyway.. enough ranting.
