user written terminal programs start incredibly slowly

Since updating to Monterey, user written terminal programs can start incredibly slowly.

For example:

% time ./a.out

Hello World

./a.out 0.00s user 0.00s system 0% cpu 1:06.23 total

%

Over a minute to start a classic a.out???

#include <iostream>

int main() {

std::cout << "Hello World" << std::endl;

return 0;

}

I have disabled malwarebytes, told "Developer Tools" to grant Terminal an exemption and examined my terminal's PATH for any inefficiency.

Running the same program over and over might be instant or minutes of delay.

Since I write and run console applications all day long preparing materials or presenting materials in class, this is killing me.

Help?

I am on an M1 MAX running 12.4.

Thanks

Apple links gcc/g++ to clang/clang++, and the following code:

#include <cstdio>
#include <iostream>

using namespace std;

int main(int argc, const char * argv[]) {
    std::cout << "Hello World" << std::endl;
    return 0;
}

When compiled as:

clang++ -Oz -o zout z.C -std=c++17

Produces these results on a 2021 16-in MBP M1 Pro w/32G running macOS 12.4:

Confirmed this impacts programs other than my own.

I am sure it is security related... or Rosetta related - something is sniffing the files before they are allowed to run. Again, I've turned off everything I can find security wise... yet the slow down is widespread. A minute or more for small programs to launch. Just isn't acceptable. Apple?
