Hmm, this looks like a buffer overrun problem to me...

I suspect that this problem is not specific to the French locale, it may
also happen with other locales too.  Not sure how significant this is at
the moment.

Please could you upload the fail.s and fail.o files ?

Are you able to capture the linker command line that gcc invokes ?
If you can tell us that as well, it might help.

Are you able to test with binutils 2.38 (available in rawhide) ?

Cheers
