Not just I can catch the OS Exceptions, I can check and alter the CPU state and decide to continue execution from an optionally modified cpu state, or just stop and show the error. It needed some work, but this seems the best way for LDC2 Win64.

For LDC, we don't do 'our own thing', but use MSVC++ EH, which allows to catch MSVC++ exceptions in D, and with some work, D exceptions in C++.

Alas not much help if you must use those other builds
Catching OS Exceptions in Windows using LDC
Hi, I'd like to catch the OS Exceptions including: - access violation - int 3 - invalid opcode etc. The default behavior is that when these events happen, the program immediately exits with some negative exit code. It was not a problem on other systems like: MSVC or Delphi, but on LDC these events are completely ignored. It would be very useful to catch these errors inside and have the opportunity to handle it whatever is the best: application exit, save important data, ignore. I've already found a solution from Adam D. Ruppe, but that's for Linux for the Access Violation case. But is there a similar thing for Windows as well? PS: I do believe rely on AccessViolation to avoid buffer overruns is really useless and unsecure. But it would be so much help for me for developing/debugging my programs. Thank You!
