Operating System: Linux 2.4
PHP Version: 4.3.2
New Comment:
I tryed stracing a httpd -X process, the last few lines was:
open("/usr/local/apache2/htdocs/horde/lib/Browser.php",
[.. cut]
read(10, "<?php\n/**\n * The Browser:: class"..., 8192) = 8192
brk(0x827e000) = 0x827e000
brk(0x827f000) = 0x827f000
brk(0x8283000) = 0x8283000
brk(0x8293000) = 0x8293000
read(10, "(\'|HotJava/([0-9]+)|\', $this->ag"..., 8192) = 7787
read(10, "", 8192) = 0
close(10) = 0
--- SIGSEGV (Segmentation fault) ---
In the /horde/lib/Browser.php, the line with that HotJava regexp is the
number 240:
} elseif (preg_match('|HotJava/([0-9]+)|', $this->agent, $version)) {
Hope this helps..
Tell me if I can help more..

The original bug might have already been fixed. :)
Could you try and find in the horde sources which line is causing this
preg_match() crash..?

With the latest cvs snap (PHP/4.3.3RC2-dev) with debug mode activated,
i get this segfault accessing /horde/, I think it's something else of
my original problem.
