looking at the dosemu code; the following bit looks a tad suspect: unsigned long int stk_ptr, stk_beg, stk_end; ... if ((fp = fopen("/proc/self/maps", "r"))) { while(fgets(line, 100, fp)) { sscanf(line, "%lx-%lx", &stk_beg, &stk_end); if (stk_ptr >= stk_beg && stk_ptr < stk_end) { stack_init_top = stk_end; stack_init_bot = stk_beg; c_printf("CPU: Stack bottom %#lx, top %#lx, esp=%#lx\n", stack_init_bot, stack_init_top, stk_ptr); break; } } fclose(fp); } do you see that printf somewhere in the logs? (afaics stk_ptr never gets initialized; what the code meant probably was if (&stk_ptr >= stk_beg && &stk_ptr < stk_end) { but the dosemu code is missing the two &'s ) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
