MediaWiki 1.16alpha (i.e. trunk/phase3), at r56407, SyntaxHighlight_GeSHi
Version 1.0.8.5 (r56284) according to Special:Version.

I see nothing relevant in the MW debug output.

I have in php.ini:
 error_reporting  =  E_ALL & ~E_NOTICE

Anyway, there seems to be more than one way to crash it with oversize inputs.
On a Special: page that uses the source tag I see:
 [Wed Sep 16 20:29:09 2009] [notice] child pid 25365 exit signal Segmentation
fault (11)

and on a mainspace page that includes a source tag I see:
 [Wed Sep 16 20:42:56 2009] [error] [client 127.0.0.1] PHP Fatal error: 
Allowed memory size of 52428800 bytes exhausted (tried to allocate 16 bytes) in
/usr/src/mediawiki-extensions-trunk/SyntaxHighlight_GeSHi/geshi/geshi.php on
line 3744

So at least some of the time it's an out of memory.  I'm going to consider
imposing a file size limit and just using <pre> for bigger ones.
