Are you sure it is something related? Which gcc version are you using?
Do you have a backtrace point to the same issue?

I am using this libc version for two months (on a CPU having ssse3
instruction set), it is also used by other distributions, so I find
strange it breaks something so common than gcc. For XOrg it can be due
to the difference in configuration, that's why the problem stayed unnoticed.
