Or not.

The problem is an array out of bounds. Because this yields undefined behaviour, some versions of gcc cause a segfault, others simply copy bogus memory to a structure field that will never be read. Other versions might do something else.

Applies to --eamt --display, --pool4 --display, --bib --display and --session --display.

This is an userspace application problem, which means it doesn't crash the kernel.

Thanks to Edgar Rodriguez for pointing this out.
