I have an exception handling frame for an Xcode application in macOS, which contains Cpp and Swift code. I am using the Unix signals frame for handling exceptions using sigaction. My sigaction signal handler get invoked when there is a swift or Cpp exception. However for some exceptions like SIGSEGV, the signal handler gets called repeatedly. To handle this I am using the SA_RESETHAND flag so that the handler gets invoked only once, and then the default action for the signal take over to terminate the process.
This approach works well when an exception occurs due to Cpp code, however when it occurs due to Swift code, the signal handler still gets invoked repeatedly. Can someone explain why is this happening and What is the solution to this?
