Package: libapache2-mod-php5 Version: 5.6.9+dfsg-0+deb8u1 Severity: normal Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? A client application connection to a SOAP server running this version of PHP on Debian Jessie was randomly getting the following error "Error Fetching http headers". This caused major issues with our client application. After further investigation I looked at the apache error logs and saw the following error every time this happened.(a lot) [Tue Jun 23 08:28:57.841494 2015] [core:notice] [pid 4038] AH00052: child pid 4085 exit signal Segmentation fault (11) * What exactly did you do (or not do) that was effective (or ineffective)? I triangulated this issue to when the SOAP server side running this version of PHP throws an exception, that is causing this Segmentation fault to occur. I modified my SOAP server side script for now to no longer "throw" any exceptions to work around this. * What was the outcome of this action? I am no longer getting Segmentation Faults in the scenarios where I knew I was getting them for sure prior. * What outcome did you expect instead? I didn't expect PHP to Segmentation Fault when "throwing" and exception over SOAP. I tried getting a coredump of this, but wasn't able to succefully do that. I did have apache running with gdb, here is a copy/paste of what I saw in there when I triggered this Segfault. ---- (gdb) run -X The program being debugged has been started already.
