I can reproduce with gcc-4.8.2 crosses targeting x86_64-w64-mingw32 -m32, both
on x86_64-linux and on i686-pc-cygwin.  On the Linux host the crash looks like:

pr60516.cc: In member function 'void Bar::foo(huge)':
pr60516.cc:8:5: internal compiler error: Segmentation fault
     }
     ^
0x7d5e8f crash_signal

0x674012 rest_of_handle_thread_prologue_and_epilogue
        /tmp/gcc-4.8.2/gcc/function.c:6973

Without -m32 it doesn't crash.  gcc-4.7.3 also crashes, but gcc-4.6.1 and 4.5.3
do not.
