* This function determines whether a memory access violation has been an
* out-of-bounds memory access in WebAssembly. If so, it will modify the context
* parameter and add a return address where the execution can continue after the
* signal handling, and return true. Otherwise, false will be returned.
* The parameters to this function correspond to those passed to a Posix signal
* handler. Use this function only on Linux and Mac.
* \param sig_code The signal code, e.g. SIGSEGV.
* \param info A pointer to the siginfo_t struct provided to the signal handler.
* \param context A pointer to a ucontext_t struct provided to the signal
* handler.
