ID: 37445 User updated by: dhrubab at gmail dot com Reported By: dhrubab at gmail dot com Status: Assigned Bug Type: PDO related Operating System: Linux PHP Version: 5.1.4 Assigned To: wez New Comment:
The two urls I provided were broken for a while but have now been relocated to the following two urls. Sorry for any inconvenience. Source: http://static.dhruba.net/bugs/37445.src.html Phpinfo: http://static.dhruba.net/bugs/37445.phpinfo.html I should also mention that I've been getting futher segfaults being caused by a variety of very different code. For example doing var_dump(); followed by exit; within a loop is causing a segfault. I'm not able to reproduce with smaller test cases. Is it okay if I give you a trace for the segfault from my own application since the smaller test cases are sometimes quite difficult to produce?

I know no C so I can't help too much, but here's my GDB trace for people that understand it. So far I can't narrow down exactly what code is causing the segfault. Reverting the diff as suggested by indeyets at gmail dot com solved the problem. ./configure --enable-debug --with-apxs2=/usr/bin/apxs2 --with-zlib --with-bz2 --with-gd --with-ttf --with-pdo-mysql --with-mysql --with-xmlrpc --with-curl Program received signal SIGSEGV, Segmentation fault.
