    CodeXL 1.6.7249 issue

    ronan.bel

      Hi, trying to use the 1.6.7249.0 with my app, CodeXL "halts" (opens a notification report window)

       

      it seems to happen when my code reaches a call to glGetTransformFeedbackVarying

       

      < outside CodeXL : valid results >

      Mode GL_INTERLEAVED_ATTRIBS - Num : 2

      SO_OUTPUT_0 : (8b52)(GL_FLOAT_VEC4)SL_SO_OUTPUT_00

      SO_OUTPUT_1 : (8b52)(GL_FLOAT_VEC4)SL_SO_OUTPUT_01

       

      < inside CodeXL : wrong results >

      Mode GL_INTERLEAVED_ATTRIBS - Num : 2

      SO_OUTPUT_0 : (0000)(UNKNOWN)

       

       

       

      < code snippet : begin >

       

      if( _u8_StreamOutputNum > 0 )
      {
      GLint iMode = 0;
      glGetProgramiv( _ui_ProgramId, GL_TRANSFORM_FEEDBACK_BUFFER_MODE, &iMode );
      glReportError( "glGetProgramiv" );
      GLint iVaryings = 0;
      glGetProgramiv( _ui_ProgramId, GL_TRANSFORM_FEEDBACK_VARYINGS, &iVaryings );
      glReportError( "glGetProgramiv" );

       

       

      const char *pz_Type;
      switch( iMode )
      {
      caseGL_INTERLEAVED_ATTRIBS:
      pz_Type = "GL_INTERLEAVED_ATTRIBS"; break;
      caseGL_SEPARATE_ATTRIBS:
      pz_Type = "GL_SEPARATE_ATTRIBS"; break;
      default:
      pz_Type = "UNKNOWN"; break;
      }

       

       

      OutputDebugStringF(
      "Mode %s - Num : %d\n",
      pz_Type,
      iVaryings );

       

       

      _u8_StreamOutputNum = min( _u8_StreamOutputNum, (u8)iVaryings );

       

       

      for( u8 i = 0; i < _u8_StreamOutputNum; i++)
      {
      charszVarBuffer[256];
      GLsizeilength = 0;
      GLsizeisize = 0;
      GLenumtype = 0;
      szVarBuffer[0] = 0;
      glGetTransformFeedbackVarying(
      _ui_ProgramId,
      i,
      256,
      &length,
      &size,
      &type,

      szVarBuffer);
