I know I might be at the wrong place with my problem, but I don't know exactly
where else to start.

I have this little problem:

Thread 1 (Thread 0x7fef46668800 (LWP 1974)):
[KCrash Handler]
#5  0x00007fef3fe6bb45 in __pthread_attr_init_2_1 (attr=0x0) at
#6  0x00007fef378c6be7 in handle_fildes_io (arg=<optimized out>) at
#7  0x0000000000000000 in  ()

this crash happens when I run Mesa compiled with clang (git) and with libc++
(git). When I use Mesa compiled against libstdc++ I can't see this crash

BTW, glibc is 2.20 from openSUSE factory and compiled against libstdc++ of

do you have an idea where the problem really comes from?

thx Michi
