For memory leaks and errors, the best way to debug is to use valgrind. 
There is a very experimental port to Mac OSX, but I think it would be a 
good first start. If you manage to make it run, run it with maximum 
verbosity (there are quite a lot of options) on the execution that 
causes errors, and send the restults to luatex-dev. Anyway, these errors 
seem quite serious :(

Thank you,
