Subject: BUG/MEDIUM: config: do not propagate processes between stopped processes
X-Git-Tag: v1.6-dev1~240
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f6b70013389cf9378c6a4d55d3d570de4f95c33c;p=thirdparty%2Fhaproxy.git

BUG/MEDIUM: config: do not propagate processes between stopped processes

Immo Goltz reported a case of segfault while parsing the config where
we try to propagate processes across stopped frontends (those with a
"disabled" statement). The fix is trivial. The workaround consists in
commenting out these frontends, although not always easy.

This fix must be backported to 1.5.
