My copy of glibc would beg to differ (_MALLOC_CHECK environ variable).
Besides, it's just very bad practice not to explicitly free resources.

This is what I am doing at the moment.  After I actually looked at the
code behind G_set_error_routine(), it became evident that it would not
work for my purposes.


It would be nice to have a virtual function for freeing resources upon
fatal error, though.
