Thanks. Providing the CRIS image wouldn't be so simple, as
neither strace nor gdbserver works at the moment.
So I am not sure it would help.
Is there a reason you use LT on X86 or MIPS?
Both have NPTL support. Normally LT is only enabled for noMMU
architectures as BFIN/FR-V/C6X/Xtensa and for some exotic
architectures AVR32/CRIS and for some architectures NPTL support
wasn't ported from Glibc as M68k/Microblate/NIOS2.
Don't get me wrong, I am happy to have someone fixing LT bugs :)
If you think LT is useful for NPTL supported architectures speak up.
best regards

I wasn't take into account that problem arise on platforms that has
HAS_COMPARE_AND_SWAP defined only. cris is not in this list.
Seems to problem come from original glibc sources and we have to fix
__pthread_unlock() itself.
Will post new version of patch after some tests.
