internal error: 0_1204 when openmp used with try-catch

Reference Number : Q625172


Version : 12.0 update 1 & 2


Product : Intel® C++ Compiler XE 12.0 u/d 1 & 2


Operating System : Windows*


Problem Description : 
The below code was reduced from a big customer project, that uses Qt. The bug is in Intel compiler,
when openmp pragma/option is used, and exception-handling is used in a particular manner, though not in other cases. The workaround is to use /Od , instead of /O2. Or, do not use openmp pragma. Also, enable /EHsc since C++ exception handling mechanism is used.

Command-line for the bug:--
icl /c /Qopenmp /EHsc qterror.cpp

compile Error :-- internal error: 0_1204

Sometimes, during parallel compilation (using /MP), when such compile errors are generated, the below error message also comes in the output.
icl: error #10298: problem during post processing of parallel object compilation

Below sample code generates the error:--

#include <iostream>  using namespace std;  #include <vector>    class myclass{};  vector<myclass>     myvec;  template <typename T>  const T &mymin(const T &a, const T &b) { if (a < b) return a; return b; }  void func(const char* ch, const char* FILE, int LINE)  {   cout << ch << " in file: " << __FILE__ << " in line: " << __LINE__ << "\n";   return;  }  bool Do()   {    myclass *j=&myvec[100];    int lines = mymin(10,100);      if(!lines)    {     {     #pragma omp parallel for //num_threads(komp_num_threads) schedule(guided)     for (int y = 0; y <= 100; y++)     {     try {     func( "Openmp error",__FILE__, __LINE__ );             }catch(std::exception e) { };     }    }    }        return 1;  }

Resolution Status : This bug has been resolved in Intel Composer 12.0 XE update 3 , 4
