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,
line 1030
