I had a look at the backtrace. Unluckily it's missing data for stack positi=
ons
1 and 2, so we don't know exactly what's happening there.

Anyway, it fails in a compare function, which is called via a pointer, so I
don't know which one that is. Some other code from some consumer set that
callback, that information can be extracted only at runtime with a debugger.

I'm almost sure the crash is caused by that compare function.

I have been unable to reproduce this crash, I'm using en_US locale, maybe
you're using a different one? That could cause string comparison errors, if=
 the
code has some defects.

Otherwise, could you recompile some more parts with debugging symbols and t=
ry
again? maybe we can catch the missing calls.
