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... committer: Markus Bröker <mbroeker@largo.homelinux.org>
