I got the latest snap, php4-200104022145, and rebuilt as you suggest. I also used a
smaller configure line:
./configure --with-apxs --enable-debug
and got the same segfault. The gdb output is identical, and the truss output is an
identical structure but a couple of different mmap base addresses and sizes.
Judging by the gdb, maybe this is a problem with either apxs on Solaris 7, or with
PHP's usage of it?
The /x/informix you see in the truss are because of the environment variables:
LD_LIBRARY_PATH=/usr/local/lib
LD_RUN_PATH=:/x/informix/lib/esql:/x/informix/lib
I will try recompiling with the static (non-apxs) form tomorrow.
Matt.

Can you please try the latest CVS snapshot from http://snaps.php.net/ ?
And I saw some informix related stuff in that truss output
so it might be something left in there. Check your php.ini
and also do 'make clean' after configuring PHP.

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).

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.

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. Full truss output can be found at
