Patch from Konstantin Isakov <ikm@pisem.net>:

Browse Source 
In most cases, dirname returns the same argument it was given, so this code
    works nice, but there's one special case: when the name contains no
    dirname, it returns "." (stored statically in the body of itself), and we
    get a segfault in attempt to free() it.
This patch fixes this problem.
