Question

我在胜利7的Qt 5.7编码。我的应用程序运行正常。但是当我使用调试器时，出现了一个错误对话框：GDB进程意外终止（退出代码3）。调试器日志的最后一部分：

>~"../../../../src/gdb-7.10.1/gdb/utils.c:1071: internal-error: virtual memory exhausted.\nA problem internal to GDB has been detected,\nfurther debugging may prove unreliable.\nCreate a core file of GDB? "

在我的代码的一部分中，我使用了QVector：

       int logic_points_number=5;
       int logic_input_points[16][logic_points_number] ;
       QVector<double> x1_1(2*logic_points_number);
       QVector<double> y1_1(32*logic_points_number);

       x1_position=x1_last_position_logic;//start from last drawn point
       for(int logic_channel=0;logic_channel<16;logic_channel++){
          for (int i=0;i<logic_points_number ;i++){
          if (logic_channel==0)// set x1_1 only for first channel
            x1_1[2*i]= x1_position;
         y1_1[(2*logic_channel*logic_points_number)+(2*i)]=(16.2-logic_channel)+(0.6*logic_input_points[logic_channel][i]);
         if (logic_channel==0){// set x1_1 and x1_position only for first channel
            x1_position = x1_position + x1_step_logic;
            x1_1[(2*i)+1]= x1_position;
          }
         y1_1[(2*logic_channel*logic_points_number)+(2*i)+1]=(16.2-logic_channel)+(0.6*logic_input_points[logic_channel][i]);
         }
       }
       x1_last_position_logic= x1_position;//Set new last drawn point
}

在运行中没有问题。当我删除上面的代码时，调试器没有问题。 google中没有有用的答案。我该怎么办？感谢

在我的情况下，错误代码是“ cdb进程意外终止（代码-805306181）”。将调试器从32位应用程序调试器更改为64位应用程序调试器可以解决此问题
