Fixed everything and it was completely user error. The calls were threaded and hence the logging was misleading as to where the crashing occurred.

Taught myself coding mainly in Java/C#, so memory issues in c are over my head. Sorry to bother you with silly issues.

Now that it's working however I just wanted to say it's running great and extremely fast. Previously I was running threads off separate dcraw library builds (ghetto, but it let me thread). This is much much cleaner and faster to boot. Thanks!!!
