Description Matthias Clasen 2005-03-04 17:12:58 UTC

gcc4 seems to miscompile gnome-menus at least on x86_64. The problem goes
away if an if-else with two identical branches is replaced by just the 
branch code.


http://bugzilla.gnome.org/show_bug.cgi?id=169200 has stacktraces and the patch

Tell me if you need any other details.

Sorry, the if-else idea was just me being shortsighted. The problem is actually
that cached_dir_add_entry is miscompiled, so that dir is valid at the entry of
the function, but when we try to access dir-entries later dir is NULL.

I have been unsuccessful in reducing this to a standalone testcase so far.

Turned out to be an unrelated 64bit problem
