Subject: [meta-oe][PATCH] wvstreams: fixing segfault with new gcc optimizations
Date: Fri,  6 May 2016 14:49:19 +0100	[thread overview]
Message-ID: <1462542559-10941-1-git-send-email-ray.kinsella@intel.com> (raw)

Recent GCC optimizations -ftree-dce and -foptimize-sibling-calls are causing
a segfault in the wvstream stackmaster. Fedora had the same problem and
resolved the issue by removing these optimizations.

See: https://bugzilla.redhat.com/show_bug.cgi?id=812651
