PHP 4.0 Bug #8298 Updated: Apache segfaults with php module loaded.

ID: 8298 User Update by: ryan@guardiandigital.com Status: Open Bug Type: Apache related Description: Apache segfaults with php module loaded. If it helps any, I was poking around through the glibc 2.1.3 ChangeLog (the version I am using) and found the following: 1999-09-12 Ulrich Drepper <drepper@cygnus.com> * version.h (VERSION): Bump to 2.1.3. * resolv/nss_dns/dns-host.c (_nss_dns_gethostbyname2_r): if res_search fails don't rely on errno value. (getanswer_r): Sett *ERRNOP in error cases. I hope this helps a little bit. I seriously hope ths is not a glibc problem. :) Previous Comments: --------------------------------------------------------------------------- [2000-12-16 15:58:58] ryan@guardiandigital.com This is very wierd. php all of a sudden stopped working when we upgraded to apache 1.3.14, and I have two different backtraces depending on the machine. This problem originated with 4.0.3.pl1, but I saw a bug report saying it was fixed in CVS so I tried the latest tarball on snaps.php.net as of Friday 12/15. Compile Options ------------ This is from the spec file I am using: compile() { ./configure --prefix=%{_prefix} --sysconfdir=/etc --with-config-file-path=/etc --enable-pic --enable-inline-optimization --with-exec-dir=%{_bindir} --with-regex=system --with-gettext --with-gdbm --enable-magic-quotes --enable-safe-mode --enable-sysvsem --enable-sysvshm --enable-track-vars --enable-ftp --with-mysql=/usr --disable-versioning --with-xml --with-zlib --enable-debug --disable-pear --disable-yp $* make } Then I am doing comile --enable-shared to build the DSO and --enable-static to build the php standalone. php.ini ------ I have played around with several options in here and I do not think it is the problem. I can supply it upon request. Machine 1 ----------- Apache only sefgaults when there is an "ErrorLog" directive inside of a "VirtualHost" directive.
