GNU libc segfaults when using POSIX.1b timers in Red Hat Enterprise Linux

Issue

While trying out a Posix test suite, a program encounters a segmentation fault when calling timer_gettime with a bogus timer id value. It is expected to result in EINVAL but instead it segfaults. Here is a code snippet to illustrate the issue:

#define BOGUSTID 9999tid = (timer_t);timer_gettime(tid, &its);

Following is the backtrace in gdb:

#0  0x000000341ae04c46 in timer_gettime@@GLIBC_2.3.3 () from /lib64/librt.so.1
#1  0x00000000004005ec in main ()
