Signal exception errors for SIGCHILD #56

Closed zwimer closed 6 years ago

Probably because of signal ignore or something.

Looking into this. SIG_IGN is simply a casted 1. Probably have to find where DynamoRIO stores signal handlers for this.

Checking the forums for a way to find the address of signal handlers when a signal is called. https://groups.google.com/forum/#!topic/dynamorio-users/gAO8PqbPxoE

Ended up utilizing the drmgr_register_kernel_xfer_event function instead of the signal event. Function
