Re: current bash.git.devel segfaults on my code

You should, with a current bash devel, just be able to run make clean make valgrind That disables some bash malloc wrapping functions that confuse valgrind severely. Then just run valgrind bash or valgrind --leak-check=full bash and see what you get. (Assuming you have valgrind installed, of course, and depending on what you want to find out). If you want to try address sanitizer, make sure you have a compiler that supports it, then run make clean make asan I put the shorthand targets in for convenience. Once you build a bash with address sanitizer support, you just have to run it and see what it reports.

I think the most fitting is EINVAL, as Robert said. Did someone tell the Linux kernel people, so they can fix this? Otherwise I will. Andrea Monaco
