Description:
------------
The notorious situation: calling imageCreateFromJpeg() terminates the calling script SILENTLY when it can't allocate enough memory, leaving no way to gracefully handle the situation. Even using set_error_handler() is useless in this case. 

This problem is widely known and talked about for a long time. While terminating a script silently is OK for a project in Programming 101 course, it unacceptable for a business website.

Please make it so this function (and all other functions in PHP) allow for graceful handling of errors. This could be throwing an exception or returning an error code.

It is by design. Out of memory (be with memory limit or system) should not allow any other operation as it can't end well anyway. Nothing can be allocated anymore, so how would we manage errors (msg, stack, etc)?

If you use a the memory limite and need more for specific areas, you can change it via php.ini (and the likes).

OK, how about this: when imageCreateFromJpeg() reaches the memory limit, it should release all memory it had been able to allocate. This will probably create enough memory for handling the error. The VM should keep enough memory in its pool to let scripts handle such errors gracefully.
