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

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).
Cheers,
Ondrej
