## #12026 — Kamesh Jayachandran — 2004-08-09T05:56:01+00:00

Hi All,
I found apache giving segmentation fault in the following scenario.
1)Disable php module and start apache.
2)enable php in the httpd.conf
3)httpd restart(Not stop and start)
4)make a request to any php page apache segfaults.
I drilled down on this issue.
My investigation is,
Apache on startup calls php_apache_server_startup twice 
one to set a user data for a userdata_key "apache2filter_post_config"
and another to call tsrm_startup and all.
While restart it simply calls this function once which misses out call
to tsrm_startup and hence tsrm_tls_table_size is just zero inside TSRM
which causes divide by zero error in THREAD_HASH_OF macro.

With regards
Kamesh Jayachandran
