Bug#1196: mailx problem with early-exiting pagers
Package: mailx
Version: 8.1-4
The `mailx' command can be made to lock up by ensuring that it twice
gets SIGPIPE/EPIPE when writing to a pager. Furthermore, once this
has happened it ignores ^C. ^Z followed by `kill' is required to
escape.
This is almost certainly due to SysV vs. POSIX vs. BSD signal
handling.
A session log showing how to reproduce the problem, followed by
environment and terminal details, is below.
