Bug description:Lack of error context with nested exceptions
Description:
------------
In short, if you thrown an exception from within the exception handler, you
get an uninformative error message with no contextual information. It
makes sense for this case to be a fatal error. We don't want to get
recursive throwing of exceptions and spiral to our death.
If you create an exception in the error handler without throwing it, it has
the correct info about where it was created. This is enough to figure out
where the error is coming from. It is at least far more informative and
gives you a starting place in a potentially complex code base.
>From my quick look at the code in Zend/zend_exceptions.c:94 where this
originates. It looks like the exception is there, and that would have
file/line num info.
Test script:
---------------
<?php
set_exception_handler("exceptionHandler");
function exceptionHandler($excp)
{
throw new Exception("Error 2");
}
throw new Exception("Error 1");
Expected result:
----------------
Fatal Error: Error 2
Actual result:
--------------
Fatal error: Exception thrown without a stack frame in Unknown on line 0
