Crash dump + source code + simple bat to run

If I compile this reduced code:

extern "C" {
    void __cpuid(int[4], int);
}

int main( void )
{
    __try
    {
        int info[4];
        __cpuid(info, 1);
    }
    __except (1)
    {
    }

    return 0;
}


With command:
clang.exe "-cc1" "-triple" "x86_64-pc-windows-msvc19.0.0" "-emit-obj"
"-fms-compatibility" "-fopenmp" "test.cpp"

Then I receive an error:
Assertion failed: CGF.CurFn && "No function in current CodeGenFunction.", file
D:\src\llvm_package_288665\llvm\tools\clang\lib\CodeGen\CGOpenMPRuntime.cpp,
