i am working on a big import script and just for fun i checked the size of $GLOBALS on every turn, and i realized it grew constantly, i found out that
pushes 2 elements on the array _PEAR_error_handler_stack, but
pop's only one off the array, so it grows on every use!

and since those are used in DB/mysql.php and File/CSV.php my memory limit comes closer with every run through the while-loop

Could you please try if the following patch (untested) works for you?

The problem with that solution is that if pushErrorHandling() has been called only once before popErrorHandling then after both array_pops are done there is nothing left in the stack to do list() on and thus the following error occurs:
NOTICE (0x08) in /usr/share/php-pear/PEAR.php on line 492
Undefined offset: 0

Maybe the list() part should be done before the 2nd array_pop?  Or is there a need for always putting both the default mode and the passed in mode onto the stack?

This solution works.  It  just takes off the extra error mode after we're done using it.
