I bet this is because --enable-sjlj-exceptions turns off the output of the
dwarf2 eh_frame which is used by the debugger to unwind the frames in most
cases if the frame pointer is omitted.
Why are you using SJLJ exceptions anyways? They are much slower when exceptions
don't happen.

I can confirm this happens on
GCC 4.7.2 x86_64 sjlj
GCC 4.6.3 x86_64 sjlj
And does not happen on (a good stack trace is obtained):
GCC 4.*.* i686 sjlj/dw2
GCC 4.8 x86_64 seh

It works if I compile the test case with -fno-exceptions.

Yes, this is related to the switch --enable-sjlj-exceptions turning off
eh_frame information
