Bug Type: Reproducible crash
Operating System: RedHat 7.2
PHP Version: 4.1.1
New Comment:
I am getting this as well, driving me nuts. Copy of email sent to
Sablotron list as well. Also: could this be due to PHP's bundled expat
possibly at all? Something to look at I guess, but then again, I'm not
that technical on the PHP internals.
The machine is Redhat Linux 7.1, PHP 4.1.1, Sablotron 0.82, Apache
1.3.23. I have followed the directions every match of a
segfault+php+sablotron+apache on google matched - recompile apache
WITHOUT it's expat_lite.
Well, I've done that. I renamed the expat_lite dir AND used the
--disable-rule=EXPAT, and did a "strings httpd | grep -i expat" and
grepped for xml as well, and did an "nm" on the binary as well - no
trace of any of that. I also removed the whole apache hierarchy to
install it fresh. However, my calls to xslt_process() still give me:

in fact, now each page load reports TWO errors. the "sabcmd" command
works fine, and is able to understand these. technically this shouldn't
be a Sablotron bug, but I was hoping someone there would have more
pointers to fix this, or find more information about it on their
side... but I think the fix will be from the PHP team.

^^ i believe that's as good as it can look. it found my system expat,
and sablotron. apache doesnt even care about expat. everything seems to
be reading from this central expat, so why doesn't it work?

I have repeatedly and on different physical machines compiled the
following:
Sablotron 0.81
Expat 1.95.2
Apache 1.3.22
PHP 4.1.1
When I run an XSLT Transform, Apache core dumps.
I get, in the error log:
[Sun Jan 20 15:12:33 2002] [notice] child pid 17404 exit signal
Segmentation fault (11)
I can use the sabcmd binary that comes with Sablotron, and successfully
transform the XML/XSLT without incident, so I don't think I have a bad
Sab compile.
Any assistance is greatly appreciated.
I am recompiling Apache with debugging, tonight.
Please email me if I can be of any help.
My configure line is : ./configure --with-apache=../apache_1.3.22/
--with-mysql --with-oci8=/home/oracle/OraHome/
--with-sybase=/usr/local/freetds/ --with-jpeg-dir=/usr/lib --with-png
--enable-track-vars --enable-tr
ans-sid --enable-sigchild --with-curl=/usr/local --with-xslt-sablot
--enable-xslt
