That's strange, perhaps I made some mistake during testing with the
packages from repo.psand.net. Is VXC_TIOCSTI enabled by default, how
to check that it is really disabled. And did you try to run the
gdb-test? Were there any errors attaching to the process or during exec?
I'll try to run test-set again from completely fresh setup as soon as
possible. (or do you have a completely sane test environment available?)
