Anyway, before I was so rudely interrupted by the "Save Changes"
button...
The commands I used are these:
[~]% ls .history
-rw-r--r-- 1 4392 Sep 1 15:07 .history
[~]% md5sum .history
d720baeeae451f88070ad3014055f0a9 .history
[~]% bash -c 'LANG=en_US.UTF-8 strace -o /tmp/tcsh.out2 tcsh'
Some interesting seeming exerpts of the trace file:
close(6) = 0
open("/home/ota/.history", O_RDONLY|O_LARGEFILE) = 0
dup(0) = 1
dup(1) = 2
dup(2) = 3
dup(3) = 4
dup(4) = 5
dup(5) = 6
close(5) = 0
close(4) = 0
close(3) = 0
close(2) = 0
close(1) = 0
close(0) = 0
fcntl64(6, F_SETFD, FD_CLOEXEC) = 0
rt_sigprocmask(SIG_SETMASK, NULL, [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [INT], NULL, 8) = 0
ioctl(6, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfe65898) = -1 ENOTTY (Inappropriate i
octl for device)
rt_sigprocmask(SIG_SETMASK, NULL, [INT], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_SETMASK, NULL, [], 8) = 0

read(6, "#+83336638\nfg\n#+1183336673\ncmake"..., 4096) = 4096
...

read(6, "\200", 1) = 1
read(6, "\215", 1) = 1
read(6, "\\", 1) = 1
read(6, " ", 1) = 1

Notice that it reads bytes in shrinking numbers from the .history file:
4096 bytes, then 170, 16, 6, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 !!BOOM!!
Odd. Anyway my tcsh and other versions are:
% tcsh --version
