This is the problem.  This isn't a direct call, it's a call through a 
cast.  If you run the -instcombine pass, I believe it will clean this up. 
Alternatively, you can prototype releaseLock in your source file properly. 
In C, use:

int releaseLock(void);

not:

int releaseLock();

... which in C are different.
