SIGTRAP at exit

[deadwood2]

As reported on https://ae.amigalife.org/index.php?topic=569.msg4672

I tried AxRuntime first, unfortunately it's not going to work for me. It was really easy to get installed and set up, but then I hit problems. A small problem is that I was building with the flags "-std=c89 -pedantic -Werror -Wall" with gcc (my project builds with Hisoft C on real Amigas, and I need to remember not to do anything modern/undefined on Linux). I removed those flags and my test program builds. But on running, it runs to completion then traps on exit:

Thread 14 "New Process" received signal SIGTRAP, Trace/breakpoint trap.
