Well, on a host on which such an condition occurs, I also have a
chroot environment with Debian Squeeze installed.
Unsurprisingly, running Lynx there doesn't lead to the problem.
What I've found surprising, however, is that if I run chroot
environment's Lynx (using all the libraries installed there)
without actually chroot'ing, it also fails to respond to SIGTSTP
correctly!
I've run chroot'ed Lynx) like:
• using schroot(1) (reacts to SIGTSTP):
$ LC_ALL=C schroot -c squeeze -- /usr/bin/lynx
(note that no Shell is involved there);
• using LD_LIBRARY_PATH (fails to react to SIGTSTP):
$ LC_ALL=C LD_LIBRARY_PATH="$p"/lib:"$p"/usr/lib \
"$p"/lib/ld-linux-x86-64.so.2 "$p"/usr/bin/lynx.cur
(locale is disabled so that the base system's /usr/lib/gconv/
isn't used; I've also used ld-linux.so from chroot.)
I've also MIME'd the /proc/LYNXID/maps file for the latter case.
Seemingly, the above rules out the possibility of a broken Shell
or library.
I should probably try to compare strace(1)'s…
