However, the counter variables accidently were signed, + thus resulting in negative indizes after integer overflow. That in turn + could lead to segfaults, but was depending on the memory layout of + the instance in question (which in turn depended on a number of + variables, like compile settings but also configuration). The counters + are now unsigned (as they always should have been) and so the dangling + mis-indexing does no longer happen. This bug potentially affected all + installations, even if only some may actually have seen a segfault. --------------------------------------------------------------------------- Version 5.1.3 [DEVEL] (rgerhards), 2009-07-28 - architecture change: queue now always has at least one worker thread |
