identifier' : unknown size
An operation on identifier requires the size of the data object, which cannot be determined.
The following sample generates C2036.
// C2036.c
// a C program
struct A* pA;
struct B { int i; } *pB;
int main() {
pA++; // C2036, size of A not known
((char*)pA)++; // OK
pB++; // OK
}
The following sample generates C2036.
// C2036_2.cpp
// a C++ program
struct A* pA;
int main() {
pA++; // C2036, size of A not known
((char*&)pA)++; // OK, if sizeof(A) == sizeof(char)
}
