How to get profile?

Hello Grzegorz,

    Sorry for late response.

    In the latest version sablevm1.1.7 I added --with-profiling=gprof to configure switch together with --with-obj-layout=traditional --with-threading=direct, after test, I got the following result which is the same as before. I can't trace the calls of subfunctions such as libsablevm.c, gc_copying, and etc.

    Could you help me find out where I had made the mistake ? 

    Thanks!
