Re: gdb doesn't show all threads, but gdbserver does

It's actually libthread_db that needs a non-global symbol from

IOW, it's a glibc feature :)


Stripping libpthread appears to be a very common mistake:

- we've seen it twice on this list in the last two weeks,
- I made it myself 4 weeks ago, even though I *knew* that libpthread
  must not be stripped.

I wonder if we should warn glibc users? Something like:

  Warning: your /lib64/libpthread.so.0 has been stripped.
  GDB will not see other threads, and multithreaded debugging will
  be unreliable.
  See http://sourceware.org/gdb/wiki/... for further info.


I consulted the GDB manual first, then google.


http://sourceware.org/gdb/wiki is an interesting source of information.
I expect to see this common mistake being mentioned there, but I can't
find it.

Anyway, thanks to everybody for all answers.
