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.

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.

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.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Applied it to 5.2.14
