Hi all,
I've built Apache/2.2.14 (Unix) in an embedded environment
(openembedded) including SSL and PHP5 modules.
SSL works fine, but PHP5 module after being loaded won't work.
With the mod_php module loaded it is not possible to get any page from
server, also even if the connection is fine (the browser doesn't show
an error message, but an empty page).
On logs I see an error message each time I try to load the page from browser:
[Thu Sep 02 18:23:54 2010] [notice] child pid 2919 exit signal
Segmentation fault (11)
[Thu Sep 02 18:24:01 2010] [notice] child pid 2917 exit signal
Segmentation fault (11)
The following is the result of launching httpd with strace (only at
the moment of SIGSEGV, since the caught of the request from browser):
