This is highly reproducible for me on Windows NT native, using games package version 1.08: I just start runxemacs.exe -vanilla and than do M-x tetris RET to get the crash in src\glyphs-msw.c at line 792 because of a NULL colorTable: Variables: - xpmimage.colorTable[i].c_color 0x00000000 "" CXX0030: Error: expression cannot be evaluated glyphs-msw.c: else if (xpmimage.colorTable[i].c_color == 0) { goto label_no_color; } } /* pick up transparencies */ => if (!strcasecmp (xpmimage.colorTable[i].c_color,"None")) { *transp=TRUE; colortbl[i]=transparent_color; transp_idx=i; goto label_found_color; }
