Windows 7 x64. Tried to compile the following:
//////////////////////////////
// FooBar.cpp by Niels Dekker
struct Foo
{
Foo() {}
~Foo() {}
};
struct Bar
{
Foo myArray[42];
Bar();
};
Bar::Bar() {}
int main() {}
//////////////////////////////
Command line:
C:\Users\NielsDekker>"C:\\Program Files (x86)\\LLVM\\msbuild-bin\\CL.exe" -cc1
-triple i686-pc-windows-msvc -emit-obj -fexceptions FooBar.cpp
Compiler output:
PHI node entries do not match predecessors!

%arraydestroy.done2.split ], [ %arraydestroy.element, %arraydestroy.body ]
label %arraydestroy.done2.split
