Re: Reminder: Illegal Package-Private Accesses in libgcj

The fix probably would have been to write
a (perhaps complicated) MD_FALLBACK_FRAME_STATE_FOR
for this and other such scenarios.

I don't think that would be necessary, at least for Java. It seems like a reasonable restriction (for us) not to try and throw through OS frames.

The problematic code idiom seems to be common
for Win32 GUI programs in C++, making DW2
useless for MinGW for the time being.

So, is the problem:

a) there is/was a bug in the unwinder that causes it to try and throw into OS frames even though you have an enclosing try block, or
b) common C++ code on windows expects to be able to throw through the OS ?
