It seems like it segfaults reading the file, not executing it. Thinking
was the regexp to cause the segfault, i tryed to delete it; the result
was that the segfault comes on the next regexp. I tryed to delete
both.. No more regexp in the function: apache segfaults reading a
comment!
So i tryed to delete some characters from the top of the file, now
apache segfaults some characters down than before, reading a comment.
(I have the full strace session, if you want)
open("/usr/local/apache2/htdocs/horde/lib/Browser.php", O_RDONLY) = 9
fstat64(0x9, 0xbfffa27c) = 0
fstat64(0x9, 0xbfffa1dc) = 0
lseek(9, 0, SEEK_CUR) = 0
lseek(9, 0, SEEK_SET) = 0
read(9, "<?php\n/**\n * @author Chuck Hage"..., 8192) = 8192
brk(0x81b8000) = 0x81b8000
read(9, "ublic\n *\n * @param strin"..., 8192) = 5945
read(9, "", 8192) = 0
close(9) = 0
--- SIGSEGV (Segmentation fault) ---

This might actually be same as bug #24563 is about.
Please try it under Apache 1.3.27.

Add some debugging echo's or something there to see what that
$this->agent contains when it segfaults.

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..
