Try adding -d yourprogram to your stap invocation. That tells stap to
explicitly load the unwind tables for the program you are probing. If
you want you can explicitly --ldd which will add unwind/symbol data for
all referenced OBJECT files.
Then you can just use print_ubacktrace() from your probe handler instead
of invoking external programs.
Cheers,
Mark
