I can't trace the calls of subfunctions such as libsablevm.c, gc_copying, and etc.

gprof doesn't work with multithreaded programs, and I couldn't get it to 
work even with the multithreading workaround (I wrote about this 
earlier, on October 26th).  Please try with qprof and libunwind and get 
back to us.
