Alternatively just close the 'aTalk' native debug window after adb install. In the sig handler it looks like the si_addr that is passed in through the siginfo_t struct is given the value 0 instead of the value of the address of the instruction causing the problem. Either make the size variables constexpr (or at least const) or use std::vector instead. If I don't register a signal handler than I get a stack overflow message.

Based on what I read, under Linux this would do exactly what I need (handle this signal for all threads), but under Windows you need to A segmentation fault is merely a highly technical term for "the program's memory is in unknown state, anywhere between some random bytes getting corrupted due to a wild pointer dereference, a buffer overrun, or something along those lines; and the program's entire memory getting replaced by an output of a cryptographic random number generator". By the way, technically your program is not a valid C++ program, as you use variable-length arrays (for example person in the SeeData function), and C++ doesn't have those. I am currently writing a mass source term UDF to implement a mass transport model in a 3D model. _beginthreadex is a MSVCRT wrapper around CreateThread that tells the runtime about the new thread. 034 5894 5894 F DEBUG : signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 0x0000763f1c9d901e 12-09 09:35:40.

You can use signal handling functions like signal() or sigaction() to catch SIGSEGV signals and execute a custom handler function. Others, such as SIGSEGV, indicate errors; these signals are fatal (they kill your program immediately) if the program has not specified in advance some other way to handle the signal.
