Works ok for me, when run directly or through valgrind.

 $ /lib/x86_64-linux-gnu/libc.so.6 | head -1
 GNU C Library (Debian EGLIBC 2.13-7) stable release version 2.13, by Roland McGrath et al.

Unfortunately "git log -p stdio/random.c" doesn't show any obviously
relevant recent changes.  Maybe using a copy of libc with debugging
symbols and getting a backtrace would help.

Sorry I have no better news, and good luck.

Jonathan
