stm32F7 emwin 显示gif导致程序死掉问题

小弟调试stm32F7+emwin  显示多边形、图片什么的都是正常的，但是当我显示gif图片时，程序直接死掉，我看了一下，程序死在了GUI_GIF_DrawSub(pFile, FileSize, XPos, YPos, j);这一句,请各位帮忙分析分析。调试代码用的是仿真例程里面的，仿真程序是可以正常跑的。
void _ShowMovie(const char * pFile, int FileSize) {
  GUI_GIF_IMAGE_INFO ImageInfo = {0}; // Info structure of one particular GIF image of the GIF file
  GUI_GIF_INFO    GifInfo = {0}; // Info structure of GIF file
  int             i;
  int             j;
  int             XPos;
  int             YPos;
  //
  // Display sample information
  //
  GUI_SetFont(&GUI_Font8x16);
  GUI_ClearRect(0, 40, 319, 59);
  GUI_DispStringHCenterAt("Show complete GIF file as movie", 160, 40);
  //
  // Show movie
  //
  GUI_ClearRect(0, 60, 319, 239);                               // Clear the image area
  GUI_GIF_GetInfo(pFile, FileSize, &GifInfo);                   // Get GIF info structure
  XPos = (GifInfo.xSize > 320) ?  0 : 160 - (GifInfo.xSize / 2);
  YPos = (GifInfo.ySize > 180) ? 60 : 150 - (GifInfo.ySize / 2);
  for (i = 0; i < 2; i++) {                                     // Show the complete GIF 2 times ...
for (j = 0; j < GifInfo.NumImages; j++) {
   GUI_GIF_DrawSub(pFile, FileSize, XPos, YPos, j);          // Draw sub image
   GUI_GIF_GetImageInfo(pFile, FileSize, &ImageInfo, j);    // Get sub image information
   GUI_Delay(ImageInfo.Delay ? ImageInfo.Delay * 10 : 100); // Use the Delay member of the ImageInfo structure for waiting a while
}
GUI_Delay(2000);                                           // Wait a while
  }
}
