Use ObjectAlloc to figure out what was allocated there.

Thanks to all who pointed out that you can't set those zombie
environment variables in main(). No wonder why they never worked for
me!
With zombies properly enabled, I now consistently get this before the
crash:
*** -[ entitiesByName]: message sent to deallocated instance

You're better off setting it in the executable's inspector. Do a Get

section.

In general, make sure to match the types of methods that you override
(the obj-c runtime does not consider types).
The signature of isEqual is:
- (BOOL)isEqual:(id)object;
Note the "id" type for the argument (however, if Browfile is an obj-c
class, then things ought to work, so I assum
