This test program fails with recent libstdc++, it seems to work ok (without recompilation) with newer libstdc++ (from gcc4.7). It also works ok on 8.2release.

Thus I believe it's caused by the recent "fixes" to libstdc++ by pfg@
>How-To-Repeat:
Download the test program http://lev.vlakno.cz/~rdivacky/test_exception.cc and compile/run on -current.
