This is similar to bug 35756 but since you have a different testcase I'll leave
this open as a separate bug. Anyways, I think I have bad headers on my system,
because my compiler chokes in that part:
$ /usr/local/bin/g++ 61759_main.mm -o test.out -framework Foundation -lobjc

Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.
And my ICE looks similar to the one I get in bug 57607 which also includes the
c++ <iostream> header...
