From c8d57dec6173430bd5602bb76efff302c51e7803 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Cyril=20Bont=C3=A9?= Date: Thu, 2 Oct 2014 19:56:25 +0200 Subject: [PATCH 20/20] BUG/MINOR: config: don't propagate process binding for dynamic use_backend A segfault was reported with the introduction of the propagate_processes() function. It was caused when a use_backend rule was declared with a dynamic name, using a log-format string. The backend is not resolved during the configuration, which lead to the segfault. The patch prevents the process binding propagation for such dynamic rules, it should also be backported to 1.5.
