This error has now disappeared for me, so I can now confirm that I'm getting
the same ICE that you originally reported:
$ /usr/local/bin/g++ 61759_main.mm -fpermissive -o 61759.exe -framework
Foundation -lobjc
during GIMPLE pass: eh
61759_main.mm: In function ‘int main()’:
61759_main.mm:4:5: internal compiler error: in objc_eh_runtime_type, at
objc/objc-next-runtime-abi-01.c:2793
int main (void)
^~~~
libbacktrace could not find executable to open
Please submit a full bug report,
with preprocessed source if appropriate.

Running in gdb gives this backtrace:

I'd need to rebuild gcc with debug info to get a better backtrace.
