That explains the compile error, but just fixing that, such as putting 
the sizeof() expressions in temporary variables, still leaves the bug, 
just hidden from the compiler.

Those two address of size parameters refer to the filled size of the 
input buffer and capacity of the output buffer.  sizeof(pointer) is just 
the number of bytes the pointer itself occupies.  It says nothing about 
the usage nor capacity of the buffer pointed to by the pointer.
