<pre>When compiling the following code I get an assertion trip in clang:
struct B {
int a;
B() : a(0xf000000B) {}
};
struct A : virtual B {
int a;
double b;
int c;
A() : a(0xf000000A), c(0xf000000A) {}
};
int main() {
A a;
}
Using the following command line:
$ (compiler32 && clang -cc1 -cxx-abi microsoft -O2 -triple=i686-pc-win32
-fno-rtti -emit-llvm testcxx.cpp)
Assertion failed: TypeSizeInBits == getDataLayout().getTypeAllocSizeInBits(Ty)
&& "Type size mismatch!", file
..\tools\clang\lib\CodeGen\CGRecordLayoutBuilder.cpp, line 1008</pre>
