[Rd] R extension memory leak detection question

[xiaoyan yu]

I am writing C++ program based on R extensions and also try to test the
program with google address sanitizer.

I thought if I don't protect the variable from the allocation API such as
Rf_allocVector, there will be a memory leak. However, the address sanitizer
didn't report it. Is my understanding correct? Or I will see the memory
leak only if I compile R source code with the address sanitizer.

 Please help!

Thanks,
Xiaoyan
