Cannot find thread XXXX: invalid thread handle

Cannot find thread XXXX: invalid thread handle

[Jose Luis Marchetti]

Hi,

This happens right after a process that my program forked exits.
I can see GDB logging thread 6151 was created when I fork the process, then later I also can see GDB logging the thread 6151 exited when the forked process exit(0).
So far so good, but then later GDB shows the error message and I can't do anything to make it work again, it respond with the error message at every command I tried ( including trying to exit from GDB ).

I have found a similar post in this list, but there is no useful answer in the reply.
Also I have seen some old posts complaining about problems with thread exit in GDB.

But I am not sure what it is. Fork is a very powerful tool to abandon.


Here is exactly what GDB shows:

[Thread 6151 (LWP 299) exited]

Cannot find thread 6151: invalid thread handle

(gdb) c

Cannot find thread 6151: invalid thread handle



Thanks in advance!
José Luís Marchetti

You have not said what target you're using or what version of GDB.
Can you try a current snapshot of GDB?
