Package: src:pcre3 Version: 2:8.39-5 Severity: grave Dear Maintainer,
the system-wide pcre3 library stack frame size detection is broken as described in https://bugs.exim.org/show_bug.cgi?id=2173 and that breaks at least ppc64el and s390x build causing segfaults in the test suite (+ autopkgtest). The patch from Sergei @ MariaDB is quite simple at it should pose no risk applying it: diff --git a/pcre/pcre_exec.c b/pcre/pcre_exec.c --- a/pcre/pcre_exec.c +++ b/pcre/pcre_exec.c @@ -509,6 +509,12 @@ (e.g. stopped by repeated call or recursion limit) */ +#ifdef __GNUC__ +static int +match(REGISTER PCRE_PUCHAR eptr, REGISTER const pcre_uchar *ecode, + PCRE_PUCHAR mstart, int offset_top, match_data *md, eptrblock *eptrb, + unsigned int rdepth) __attribute__((noinline,noclone)); +#endif static int match(REGISTER PCRE_PUCHAR eptr, REGISTER const pcre_uchar *ecode, PCRE_PUCHAR mstart, int offset_top, match_data *md, eptrblock *eptrb, Please apply the patch in the next maintenance window for PCRE3, including stable and possibly oldstable as this causes segfaults (at least) in src:mariadb-10.1 on affected platforms (and both ppc64el and s390x are our release architectures).
