Introducing PSEH 2.0. It only wants to be loved. Highlights of this version:
- PSEH 2.0 syntax is 99% compatible with native SEH syntax
- PSEH 2.0 binary code a vast improvement over 1.1 - no more setjmp, no bogus loops, no weird optimizer behavior
PSEH 2.0 is a horrible, GCC-only, x86-only hack. It makes several non-portable assumptions and hey, did you know __builtin_frame_address(0) is *not* the same thing as EBP? Overall, it must be a world record for compiler abuse
PSEH 2.0 is, sadly, not binary-compatible with PSEH 1.1, although I will almost certainly unify the implementation at a later time
PSEH 2.0 needs testers. And love.
Not implemented yet: returning from a SEH block (i.e. _SEH2_YIELD())
Example of 2.0 syntax (yes, _SEH2_END is unavoidable):
_SEH2_TRY
{
_SEH2_TRY
{
/* ... */
}
_SEH2_EXCEPT((/* ... */))
{
/* ... */
}
_SEH2_END;
}
_SEH2_FINALLY
{
/* ... */
}
_SEH2_END;

Happy early birthday, Aleksey.
