I want to handle Parse_Errors and similar Fatals with my custom error handler when they occur in eval()'d code.

This is necessary when i want to execute custom code in my console script and prevent this code from crashing my entire program if there is only a simple typo in there...

I have achieved this by a little hack in the "zend_execute.c" but i don't know if this handles any errors right that don't occur in eval'd() code...
This is what i changed (to even prevent a segmentation fault) (zend_execute.c, line 1563):

if (zend_hash_find(active_function_table, function_name->value.str.val, function_name->value.str.len+1, (void **) &function)==FAILURE) {
zend_error(E_USER_ERROR, "Call to undefined function: %s()", function_name->value.str.val);
return;
}
