fix free of uninitialized buffer pointer on error in regexec the fix in commit c3edc06d1e1360f3570db9155d6b318ae0d0f0f7 for CVE-2016-8859 used gotos to exit on overflow conditions, but the code in that error path assumed the buffer pointer was valid or null. thus, the conditions which previously led to under-allocation and buffer overflow could instead lead to an invalid pointer being passed to free.
