PHP 4.0 Bug #10072 Updated: SIGSEGV on startup (apxs)

ID: 10072 User Update by: old.wolf@project-w.com Old-Status: Feedback Status: Open Bug Type: Reproduceable crash Description: SIGSEGV on startup (apxs) I'm not sure what you mean. My PHP configure line already has --enable-debug, and contains no source dirs except jpeg-6b (I can take that out and recompile I guess). ../../mysql = /usr/local/mysql, which is where it installed Or are you referring to my Apache configure line (the example installation specified to use those source dirs). Previous Comments: --------------------------------------------------------------------------- [2001-03-30 14:37:24] sniper@php.net 1. Delete config.cache 2. Add --enable-debug into your configure line 3. Configure and compile and try regenerating that gdb backtrace. And do not use the source dirs in any other configure option of PHP than --with-apache. You should be using the INSTALL base dirs. --Jani --------------------------------------------------------------------------- [2001-03-29 23:40:15] old.wolf@project-w.com OS version: SunOS ptl2 5.7 Generic sun4u sparc SUNW,Ultra-5_10 Apache 1.3.19+mod_ssl-2.8.1 configure line: EAPI_MM=../mm-1.1.3 SSL_BASE=../openssl-0.9.6 ./configure --prefix=/usr/local/apache --enable-module=ssl --enable-module=so --enable-module=rewrite PHP 4.0.4pl1 configure line: ./configure --with-apxs --with-mcrypt --with-mhash --with-mysql=../../mysql --with-gd --enable-versioning --with-ttf --with-jpeg-dir=../jpeg-6b --enable-debug If the LoadModule libphp4.so is removed from httpd.conf, Apache operates correctly. Otherwise, there is a SIGSEGV as httpd starts up. Following is a GDB backtrace and partial truss output.
