getpwnam_error.c:
* The memory hole can be fixed with two different approaches
1) Change /etc/nsswitch.conf: passwd: compat to passwd: files
2) LD_PRELOAD=/lib/libnss_compat.so.2 valgrind ./getpwnam_error
GLIBC loads libnss_compat on the fly and unloads it.
Thanks to telexicon for reporting this...
