            Bug ID: 44760
           Summary: stop-hook doesn't work when user make ctrl-c interrupt
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: MacOS X
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org
          Reporter: slei.casper at gmail.com

lldb doesn't consider stop-hook when user make ctrl-c interrupt.
step to reproduce:
1. write the following content to /tmp/a.py
```
def __lldb_init_module(debugger, internal_dict):
    debugger.HandleCommand('target stop-hook add --one-liner "register read
rax"')
```
2. debug any program with the following lldb command
(lldb) target create "./a.out"
Current executable set to './a.out' (x86_64).
(lldb) command script import "/tmp/a.py"
Stop hook #1 added.
(lldb) r
     rax = 0x0000000000000000

Process 9563 launched: '/tmp/a.out' (x86_64)
Process 9563 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP
    frame #0: 0x00007fff6b9babba libsystem_kernel.dylib`__semwait_signal + 10
libsystem_kernel.dylib`__semwait_signal:
->  0x7fff6b9babba <+10>: jae    0x7fff6b9babc4            ; <+20>
    0x7fff6b9babbc <+12>: movq   %rax, %rdi
    0x7fff6b9babbf <+15>: jmp    0x7fff6b9b968d            ; cerror
    0x7fff6b9babc4 <+20>: retq
Target 0: (a.out) stopped.



expected: after user make ctrl-c interrupt, lldb should print rax register, but
lldb doesn't print it.
