Yes, that's true. I had another look and the esoteric part that I was
remembering was extracting the exception message from within the same
SEH handler. Getting the stack trace is relatively trivial.

sometimes sparks religious debates) but it does let you catch and unwind
more exception types than /EHs does, which is sometimes handy, albeit
with a performance cost.

Also /Oy- helps with getting stack traces in general (GCC equivalent is
