If this ErrorDocument is triggered, then apache child crashes. It must be connected with the bug #33987 and as ironic it is, PHP 4.4.1 Changelog claims, that #33987 is fixed. Bug #33987 is actually reported against PHP5.1 and not against 4.4.0. PHP 4.4.0 works fine with ErrorDocuments. --------- I looked into the apache2handler source (sapi/apache2handler/sapi_apache2.c) and after debugging it was clear, that crash happens on line (538): if (parent_req && strcmp(parent_req->handler, PHP_MAGIC_TYPE) && strcmp(parent_req->handler, PHP_SOURCE_MAGIC_TYPE) && strcmp(parent_req->handler, PHP_SCRIPT)) { If changed to this: if (parent_req && parent_req->handler && strcmp(parent_req->handler, PHP_MAGIC_TYPE) && strcmp(parent_req->handler, PHP_SOURCE_MAGIC_TYPE) && strcmp(parent_req->handler, PHP_SCRIPT)) { then everything's fine and works. The correct extra check is present in 5.1.0 (but for some odd reason not in 4.4.1 and 5.0.5). Reproduce code: --------------- .htaccess --------- ErrorDocument 404 /error.php?status=404 /error.php --------- die( "File Not Found!" ); Expected result: ---------------- File Not Found! Actual result: -------------- Apache2 crashes. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35056&edit=1
