cygwin gdb 程序收到信号？，未知信号

Question

my.cpp:

#include<stdio.h>
int main()
{
  printf("hello main");
  return 0;
}

用 gcc 构建然后我使用 gdb 来运行程序，发生错误。 gdb: 未知目标异常 0x406d1388 在 0x75fca6f2

Program received signal ?, Unknown signal.

这是此版本 GDB 的已知错误。 This link 可能对你有帮助。

Answer 2

当我把我的cygwin换成64位的时候，问题居然解决了。我认为这可能是另一个不同于 "well-known" GDB 错误的错误。
