Sorry, but if you say "I have a version of GDB three years old and it
has this problem", we're only going to suggest you try the current
version.  We've spent those three years fixing problems in GDB.

I don't know what this might be.  My first guess would be that the
system you're building on didn't have tkill available.

It debugs it!  Debugging, especially for threaded programs, is
intrusive and complicated.
