gdb gets SIGSEGV before calling main()

[Jim Starkey]

This about covers it:

jas@rpi3:~$ cat foo.cpp
#include <stdio.h>

int main (int argc, const char **argv)
{
        printf("hello, world\n");

        return 0;
}
jas@rpi3:~$ g++ foo.cpp
jas@rpi3:~$ gdb a.out

I can't image how this can be. It seems to happen on all images.

apt-get upgrade reported that gdb was up to date. However, removing and re-installing gdb with apt-get got it working again.

The gdb packaging? The upgrade procedure?

I have a copy of the systems with bad gdb instances if anyone would like to take this on.

But for now, I'm out of the woods...
