Yes that's necessary. I should have mentioned that in the first email - shame
on me :(
Libunwind by default doesn't supply the necessary _Unwind_* functions for
exception handling.
So, the default unwinding routines of gcc are used even though you preload
libunwind.so.
And the result is obviously the same as without preloading libunwind.so.
