How to recover from a fatal error "Allowed memory size exhausted"

Question

Do you know any solution to recover from the PHP fatal error : "Allowed memory size ... exhausted"

I have a shutdown function that is called when a fatal error appear. This function create an ErrorException from it, and logs it.

The problem is : when there is no more memory available, it can't log the error (I log in Firebug, via FirePHP, with Zend Framework).

So what i mean by "how to recover from it", is how to perform basic error log, and let Zend Framework send the Headers, so that the error is logged (in Firebug in my case) as any other error ?

Thanks

This worked fine for me:

try {
    ini_set('memory_limit', (ini_get('memory_limit')+1).'M');
} catch(Exception $e) {}

This assumes your memory limit is in the format 123M.
