I'll confirm that this is a new regression and that it is also present on Cygwin.

Furthermore I'll state that though installing a blocker insn is basically a
kludge, fixing the C++ sjlj 'feature' that fooled the compiler into thinking
that it was perfectly OK to write to memory that wasn't yet allocated is not
nearly as simple nor would it be as target specific.

So I would say go for putting the kludge back :)

I'll also confirm that Danny's patch fixes the same error under Cygwin.
