I could solve some problems in my C library bindings using ltrace. It logs 
all calls to external C libraries together with the function parameters. 
You can create a config file in order to improve reporting of passed 
parameters.

Another useful tool might be valgrind. I think it should also point you to 
the crashing function call.
