Re: Can C pointers take C++ addresses?

Hi all,

I'm calling C++ functions from C, and been having memory problems.
Specifically, I'm calling a C++ function from C that returns a char*.
I'm allocating memory for the returned pointer in the C++ function,
and trying to free its memory in the C code.
Something as:

// ---------C++ code ------------
extern "C" char* convert() {
   char* rvo;
   rvo = (char*) malloc(10);
   ...
   return rvo;

}

// ---------- C code --------
int main() {
   char* s = convert();
   free(s);
   s = convert();
   free(s); // here is the problem!

}

Both functions are compiled independently, and then linked together to
form an executable.
I'm getting a "Bus error" when trying to deallocate the second time,
and not sure why.
Is there any problem with this procedure? Is it safe to allocate
memory in C++ code, assign it to C pointers, and then deallocate them
in C?

Thanks very much
