--- Comment #5 from James Y Knight <foom at fuhm dot net> ---
The originally-reported program still appears to exhibit the issue.
Just looking at the unwind code -- and without attempting to test anything --
it appears that the solution may be as simple as inserting two lines:
if (found_type == found_terminate)
return _URC_FATAL_PHASE1_ERROR;
at line 651 of eh_personality.cc
(https://github.com/gcc-mirror/gcc/blob/b85a03ae11b157d60ddf93b71632efe0bde3bafd/libstdc%2B%2B-v3/libsupc%2B%2B/eh_personality.cc#L651)
I believe that would abort the search phase (similarly to what happens if you
run out of unwind frames before finding any catch handler) and cause
_Unwind_RaiseException to return _URC_FATAL_PHASE1_ERROR, which then causes
_cxa_throw to call terminate().
