(gdb) ------------------------------------------------------------------------ [2011-11-10 19:06:09] ecrist at claimlynx dot com Tried the patch attached to this report against 5.3.8 and we get more segfaults than before. Additionally, we've added a call session_write_close() to every page and that also doesn't solve the problem for us. I can provide backtraces or anything else needed to aid a solution to this bug. ------------------------------------------------------------------------ [2011-11-09 21:49:37] ecrist at claimlynx dot com This bug is seen on FreeBSD 8.2-STABLE as of Nov 4, 2011 with PHP 5.3.8 on Apache 2.2.21 and Postgres 8.4.9. ------------------------------------------------------------------------ [2011-07-12 14:00:25] me at dzonder dot net This bug still exists on PHP 5.3.6 (FreeBSD 8.2 official port). My workaround is to explicitly call session_write_close() in scripts where sessions with pgsql are used. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
