The latest snapshot, won't compile, here's the fix:

Compile error:
mod_php4.c: In function `php_apache_startup':
mod_php4.c:252: too many arguments to function `php_module_startup'
mod_php4.c: At top level:
mod_php4.c:354: warning: initialization from incompatible pointer type
make[3]: *** [mod_php4.lo] Error 1
make[3]: Leaving directory _src/php4-200101030145/sapi/apache'

FIX:
$ diff sapi/apache/mod_php4.c sapi/apache/mod_php4.c.old
252,253c252
< /* too many arguments fix: if(php_module_startup(sapi_module, NULL) == FAILURE */
< if(php_module_startup(sapi_module) == FAILURE 

---
>     if(php_module_startup(sapi_module, NULL) == FAILURE

The XML bug is fixed though!
Thanx!

I tried the latest CVS and it doesn't crash.
Please try the latest CVS snapshot from http://snaps.php.net/

Reporting back:

php 4.0.3pl1 doesn't expose this error, under the same chrooted environment, with the same server-software.

First of all:
Best wishes to you all!

Now for the annoying stuff:

This bug seems similar to 8492.

Offending code, remove the /* */ and it core-dumps:
$xml_file='bla.xml';
if (!(list($xml_parser, $fp) = new_xml_parser($xml_file))) {
    die("could not open XML input");
}
print "<pre>";
while ($data = fread($fp, 4096)) {
/*	if (!xml_parse($xml_parser, $data, feof($fp))) {
	die(sprintf("<span style='color: red; font-weight: bold'>XML error: %s at line %d</span>n",
		xml_error_string(xml_get_error_code($xml_parser)),
		xml_get_current_line_number($xml_parser)));
	}*/
	echo $data;
}
print "</pre>";
xml_parser_free($xml_parser);

Output BSDi gdb backtrace:

Program terminated with signal 11, Segmentation fault.
#0  0x48253c7b in zend_hash_exists (ht=0x816273c, arKey=0x8047d0c "
