Bug ID: 17767
Summary: [-cxx-abi microsoft] C++ class improperly laid on top
of another
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
consider:
#include <stddef.h>
#include <stdio.h>
#include <string.h>
char buffer[419430400];
inline void *operator new(size_t, void *pv) { return pv; }
struct TypeName0 {
TypeName0() {
printf("Typename0 - this: %llu\n", (unsigned long
long)((size_t)this - (size_t)buffer));
}
};
struct TypeName2: public TypeName0 {
char TypeName2FieldName0;
TypeName2() {
printf("Typename2 - this: %llu\n", (unsigned long
long)((size_t)this - (size_t)buffer));
printf("Typename2 - Fiel: %llu\n", (unsigned long
long)((size_t)&TypeName2FieldName0 - (size_t)buffer));
}
};
struct TypeName3: public TypeName0, public TypeName2 {
TypeName3() {
printf("Typename3 - this: %llu\n", (unsigned long
long)((size_t)this - (size_t)buffer));
}
};
int main() {
memset(buffer, 0, sizeof(buffer));
new (buffer) TypeName3;
}
clang gives:
Typename0 - this: 0
Typename0 - this: 0
Typename2 - this: 0
Typename2 - Fiel: 0
Typename3 - this: 0
msvc gives:
Typename0 - this: 0
Typename0 - this: 1
Typename2 - this: 1
Typename2 - Fiel: 1
Typename3 - this: 0
