Doesn't crash for me:
php -q
<?php $a="abc123";
echo ereg_replace("123",'def\1ghi',$a)?>
abcdef\1ghi

Errm...
That test passes here too:
\0 back reference
... passed
But this one doesn't:
nonexisting back reference (012.phpt)
... failed
(it crashes)

With my configuration it passes.
Running tests in /home/yohgaki/cvs/php/DEV/ext/standard/tests/reg
=================================================================
\0 back reference
... passed
However, there is something wrong in current PHP. I got exit status 255
when run-tests.php finished. (It doesn't now)
The real problem may be in broken heap memory area by some other
place.

The testscript ext/standard/tests/reg/012.phpt (" nonexisting back
reference") causes PHP to segfault:

echo ereg_replace("123",'def\1ghi',$a)?>
