I have run into what I think is the same bug in 4.3.3 under SunOS 5.7
with apache 2.0.47 all compiled with gcc
331 rroberts> gcc --version
gcc_bin (GCC) 3.2-gnupro-03r1

The particular problem shows up when attempting to use
class.rFastTemplate.php which has a preg_match looking for unmatched
template variables. The script *always* times out and the reported
error is always on preg_match.
The difference is that the preg_match is merely long-running, not
forever running. However with PHP 4.3.1 on RedHat 8.0, I do not see
this behavior. I can put together a test case, but I didn't see the
point other than pointing out that it does *not* appear to be Win32
only.

Reproduced with latest CVS (under Windows XP), PHP as Apache2 module.
Works fine with CLI.

Description:
------------
PHP aborts without any message or runs forever in below case.
Platform: Windows XP Pro, Apache2.0.46, PHP4.3.3
For example, in preg_match('/a(?:.)+z/',$str,$match), the length of
string matched between 'a' and 'z' is more than approximately 1KB. It
always appears. According to the length, PHP aborts without any message
or runs forever.
It also appears in preg_match('/a(?>.)+z/',$str,$match), but does not
appear in preg_match('/a(.)+z/',$str,$match) and
preg_match('/a.+z/',$str,$match).
Actually, I want to use
preg_match_all('/<tr[^>]*>((?>.(?!<\/tr>))+.)<\/tr>/is',$str,$matches)
and so on.
Reproduce code:
---------------
$str =<<<EOD
a

EOD;
preg_match('/a(?:.)+z/s',$str,$match);
echo $match[0];
// It cannot reach the 'echo $match[0];'.
Expected result:
