It seems it catches an exception and attempts to print a backtrace, gets
a SIGSEGV in libexecinfo which is caught by a signal handler where it
attemps again to print a backtrace. It gets a SIGSEGV again for the same
reason, and gives up. I am not sure there is any recursivity at work
there, just a double fault.

For now it has nothing to do with libunwind. The thing just crashes with
backtrace() from libexecinfo. The place where libunwind could be
required is where it prints a backtrace for a given ucontext_t, but that
it not the place where it crashes for now.

If you want to give it another try, here are my patches so far:
