            Bug ID: 15648

           Product: glibc
           Version: unspecified

Hello,

I build a program with gcc 4.6 and enable link time optimization.
when static linking, ld show error mesage 

/usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libpthread.a(lowlevellock.o):
In function `__lll_lock_wait_private':

I also search relative issue like
http://dev.drobilla.net/ticket/914

I see the glibc source files
libc/nptl/sysdeps/unix/sysv/linux/libc-lowlevellock.c:

#include <lowlevellock.c>

I am confused. Why nptl and libc share the same context?
Is it a potential bug?

I make the patch, and the problem is resolved.
Is this correct for arm?
