From 2e2bc535bd03df86f78b648f78d2d0a95d273fab Mon Sep 17 00:00:00 2001 From: Andrew Deason Date: Mon, 21 May 2012 17:11:29 -0500 Subject: [PATCH] afsd: Avoid dir interpolation for memcache memcache doesn't make use of fullpn_DCacheFile, fullpn_VolInfoFile, etc. Do not even try to generate these strings for memcache, since cacheBaseDir will be NULL, and so this can cause a segfault on some platforms including Solaris.
