21 /* Some versions of glibc 2.7 has a bug in strtok_r when with optimization that
22 * can cause segfaults:
23 * http://sources.redhat.com/bugzilla/show_bug.cgi?id=5614.
25 * Open vSwitch works around this problem by supplying a replacement string.h.
26 * This test program verifies that the workaround is in place.
