memory leak of C functions with pprof WriteHeapProfile

[Pavan]

Hi, I am debugging memory leak in a go application. It has lot of C functions called with in. 

I am trying to use pprof.WriteHeapProfilepprof to dump the memory allocations .

after generating dump file with WriteHeapProfile, it doesnt indicate memory allocations with-in C functions. 

ex: If i call C.greet function and do lot of mallocs inside C function, greet, it doesnt indicate the greet function. 

Please let me know if there are other profilers when C functions are involved with go programs. 

Regards,

Pavan

Thanks for the link. even valgrind gives good info on go binary for C functions.
