Compilation of the following test:

void foo(); 
void bar(); 

int main () 
{ 
#pragma omp parallel 
  { 
    try { 
      foo(); 
    } 
    catch (int t) { 
#pragma omp critical 
      { 
        bar(); 
      }; 
    } 
  }; 
  return 0; 
} 

clang -fopenmp --target=x86_64-pc-windows-msvc t.cpp -c

Result in:

Instruction does not dominate all uses!
  %2 = catchpad within %1 [%rtti.TypeDescriptor2* @"\01??_R0H at 8", i32 0, i32*
%t]
  %0 = call i32 @__kmpc_global_thread_num(%ident_t* @0) [ "funclet"(token %2) ]
fatal error: error in backend: Broken function found, compilation aborted!
