           Summary: pcre_free_study should not try to dereference a NULL
                    pointer
           Product: PCRE
           Version: 8.21
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: bug
          Priority: low
         Component: Code
        AssignedTo: ph10@???
        ReportedBy: dangelog@???
                CC: pcre-dev@???

In order to keep free(3) semantics, it should not harm to pass a NULL pointer
to pcre_free_study. Instead, the pointer gets dereferenced leading to a crash
(cf. pcre_study.c line 1381).
