At this point we know for sure that the issue is not armhf-specific, and also that it is not caused by stack-clash-protection. On the contrary, enabling stack-clash-protection on armhf allowed us to discover a problem that would have otherwise gone unnoticed. Whether the bug is in plplot or gfortran I really have no idea. I would tend not to think of a compiler issue unless we have some evidence in that direction though, and suggest raising the issue with plplot upstream. Showing them the x86 reproducer with -fsanitize=address should be a good starting point. Thanks, Emanuele
