macos - gdb 在 mac os catalina 上调用 `run` 后挂起

Question

系统:

mac osx catalina (10.15.5)
gfortran 9.3.0 (from homebrew)
gdb 9.2 (from homebrew)

经历并遵循以下说明:
https://sourceware.org/gdb/wiki/PermissionsDarwin

试图调试这个程序只是为了学习:

! test.f90
program main
  integer :: val
  val = 1
  print *, val
  val = 2
  print *, val
end program main

编译:

gfortran test.f90 -Og -g -o test

然后在终端

~/Coding/gdb
> ./test
           1
           2
~/Coding/gdb $
> gdb test

在这一点上什么也没有发生......它只是挂起并且无法用Ctrl-C杀死它，我必须去事件监视器杀死gdb。想知道我是否在设置中遗漏了什么，或者是否有人有任何其他想法为什么这可能是

Answer 1

您可以使用 Ctrl-Z 终止挂起。
尝试运行几次，正确设置后它似乎只在某些时候工作。
