Bug#792423: apache2.2-bin: Segfault at timeout with a no-output CGI
Package: apache2.2-bin Version: 2.2.22-13+deb7u4 Severity: normal Dear Maintainer, I got this problem because blocked CGI were not killed after timout and instead I got in the error log something like: [Tue Jul 14 17:16:30 2015] [notice] child pid 11032 exit signal Segmentation fault (11) I can reproduce this one creating a doing nothing CGI like this one: http://gapil.truelite.it/sources/browser/trunk/sources/testsignalcgi.c installing in /usr/lib/cgi-bin and asking it with a browser. At the timout the result is a segfault in the apache child that launched the CGI, before it can send the SIGTERM to the CGI. This behaviour disappear if I remove mod_deflate and restart apache. I already got this bug in Lenny (only for 64 bit platform), but it's not present in Squeeze. I cannot test it in a 32 bit machine (that I don't have).
