Bug description:php cli & apache crash
Description:
------------
Hi PHP DEV team.
My system have a crash problem.
My PHP installed from FreeBSD ports system.
My apache always complain look like
[Thu Sep 30 11:47:21 2010] [notice] child pid 96860 exit signal Illegal
instruction (4)
[Thu Sep 30 11:48:52 2010] [notice] child pid 62054 exit signal
Segmentation fault (11)
And php cli also problem like
# php
Segmentation fault (core dumped)
But I cleared my extensions.ini empty, php cli work fine.
I can't identify extensions cause crash, Because random extensions cause
crash.
Under is my extensions.ini
extension=fileinfo.so
extension=imagick.so
extension=memcache.so
extension=apc.so
extension=zip.so
extension=mysqli.so
extension=simplexml.so
extension=mysql.so
extension=hash.so
extension=gettext.so
extension=ctype.so
extension=gd.so
extension=ftp.so
extension=bz2.so
extension=xml.so
extension=openssl.so
extension=mbstring.so
extension=mcrypt.so
extension=json.so
extension=imap.so
extension=ldap.so
extension=iconv.so
extension=filter.so
extension=readline.so
extension=session.so
extension=xmlrpc.so
extension=zlib.so
extension=dom.so
Today I tried set PHP debug complier flag, and use GDB for debug.
GDB debug output in Actual result.
Please help for debug
Thanks very much.
Expected result:
----------------
See 'NO SEG FAULT' printed to screen and work fine
Actual result:
--------------
# php
Segmentation fault (core dumped)
# gdb /usr/local/bin/php ./php.core
Core was generated by `php'.
Program terminated with signal 11, Segmentation fault.
