This is a strange one, it only happens with "read -d" (change delimiter)
and only when piping the output. It's present as far back as 4.3.11.
torch% read -d '' | head
zsh: bad tcgets: bad file descriptor
GDB trace from the current source is appended.
Incidentally, the oldest tagged version of zsh I can build from git is
4.3.10. Any version 4.3.9 or older that I tried, generates pre-build
errors such as bad configure.ac files or failure to complete mkmakemod.
I suspect tags were incompletely or incorrectly applied when importing
