> Removing 1990 also didn't fix it.

Argh, I overlooked this comment. Now, *that* gives me something to think
about...

CVE-2006-0996.patch: only affects phpinfo()
CVE-2006-1490.patch: only affects php_unescape_html_entities()
CVE-2006-1494.patch: only affects tempnam()
CVE-2006-1608.patch: only affects copy()
CVE-2006-2563.patch: only affects the curl module
CVE-2006-3011.patch: only affects error_log()
CVE-2006-3018.patch: only affects session module, straightfoward patch

According to the backtraces, none of above seem to be an issue here.

The remaining two patches do seem to be related to your crash:

CVE-2006-1990.patch: affects low-level memory handling in Zend (_emalloc() and 
_efree())
CVE-2006-3017.patch: affects zend_hash_del_key_or_index()

However, if removing both of them still lead to the crash, then I'm
seriously confused. Then the only remaining possibility is that some of
the 'innocent' patches created a side effect which causes a crash later.

I'm still unable to reproduce the crash, so I'm afraid I have to ask you
to continue to debug this. With bisectioning (i. e. halving the set of
patches), you should be able to pinpoint the offending patch in three
steps. Thank you!
