-Status: Bogus
+Status: Open
Bug Type: Reproducible crash
Operating System: FreeBSD 4.10-RELEASE-p5
PHP Version: 4.4.3
New Comment:
We've had another customer report regarding this issue on a completely
different server, same back trace but this time using PHP 4.4.2 and
4.11-RELEASE-p19
Is there anyway to produce more information that might help track this
down?
The configure line is:
'./configure' '--enable-versioning' '--enable-memory-limit'
'--with-layout=GNU' '--with-config-file-scan-dir=/usr/local/etc/php'
'--disable-all' '--with-regex=php' '--disable-cli'
'--with-apxs=/usr/local/sbin/apxs' '--disable-ipv6'
'--prefix=/usr/local' 'i386-portbld-freebsd4.11'
tokenizer was built as a seperate module afterwards using the
php4-tokenizer port.

I edited the ports Makefile to add --enable-tokenizer and removed the
tokenizer as an extension and there was no crash.
I tried a similar setup on my debian box following the same procedure
with tokenizer as an extension and had no problem. I'm going to look a
little closer later on and see if I can identify what in particular is
causing this on the FreeBSD box.

Works just fine on Linux and FreeBSD 5.4-RELEASE.
