The module I'm loading has the line 
emalloc(100);
in the function for ccmfactory_new()
I know I need to efree it.  However, as a test I'm not freeing it.  

At line 551 of main.c t->filename is pointing to invalid memory.
In _emalloc it is getting set to valid memory with valid data...

Let me know i you have any questions...

Attached is my gdb session:
