[PSEH3] - Do not try to dereference potentially invalid pointers. The FrameRegister->ExceptionPointers pointer is only valid in the context of the filter function. Indeed, the PSEH3 exception handler allocates it on the stack, and when control gets back to the __excep { } coder, ebp and esp were already restored to their original values, so whatever can happen to those pointers. Investigation and debugging mastered by Thomas Faber, whose efforts were shamelessly stolen by me to improve my commit statistics.

[PSEH] - On clang builds we need to do the return twice trick, since we don't have asm goto, which would allow us to specify labels in the code where we can branch to on an exception. So we return back to from where we called the registration function and decide how to proceed from there nasedon the return value. For this we need to save the return address in the registration record and use it in __SEH3$_InvokeEmbeddedFilterFromRegistration svn path=/trunk/; revision=64078 2014-09-07 21:40:07 +00:00			`#define SEH3_REGISTRATION_FRAME_ReturnAddress 48`
