PHP Bug Type: Reproduceable crash
Bug description: Calling zend_error during module shutdown causes PHP to crash.
If you call zend_error during the shutdown sequence for a module then you
get a core because there is no longer a valid error_filename.
We eliminated this from our code, at some cost to its generality, but then the same
error occurs if, eg, you can't rollback your oracle transaction during
the shutdown of the Oracle module.
Simple fix: in zend_error, test to see if you are in the middle of shutdown
and don't attempt to write to error_filename if so.
Better fix: close error_filename AFTER all the modules are shutdown.
Traceback follows:
