Description
Running ksh93 in snv_111 (actually the Indiana build 111 bits, not 111a).
gw:~> ksh93
<email address omitted>:~$ ls -l .tramp_history
.tramp_history: No such file or directory
<email address omitted>:~$ HISTFILE=/export/home/richlowe/.tramp_history
zsh: segmentation fault (core dumped) ksh93
gw:~> pstack core
core 'core' of 1620: ksh93

(note the 2nd arg to strcmp)
However, if HISTFILE is unset first, all is fine:
gw:~> ksh93
<email address omitted>:~$ unset HISTFILE
<email address omitted>:~$ HISTFILE=/export/home/richlowe/.tramp_history
<email address omitted>:~$
Frequency
Always
Regression
No
Steps to Reproduce
Alter HISTFILE without first unsetting it (it maybe important that the file
does not currently exist?)
Expected Result
HISTFILE appropriately changed, all is well.
Actual Result
SIGSEGV strcmp'ing a second arg of NULL
Error Message(s)
Test Case
Workaround
unset HISTFILE before altering it.

*** (#1 of 3): 2009-04-25 01:45:30 GMT+00:00 <User 1-F4SZV>
I've attached a core file from Rich to the bug report.
*** (#2 of 3): 2009-04-25 07:39:28 GMT+00:00 <User 1-5Q-13979>
This can be easily reproduced by simply typing
$ env - ksh93
myprompt$ HISTFILE=/tmp/somefile
*** (#3 of 3): 2009-04-25 07:43:01 GMT+00:00 <User 1-5Q-13979>
=== *Public Comments* ========================================================
I was also able to reproduce this, and further testing with Rich noted
that it only applies when HISTFILE is in its default unset state, and
that changing HISTFILE in .profile appears to make you immune.
*** (#1 of 1): 2009-04-25 05:03:50 GMT+00:00 <User 1-5Q-1267>
=== *Workaround* =============================================================
Set HISTFILE in $HOME/.profile.
*** (#1 of 2): 2009-04-25 05:03:50 GMT+00:00 <User 1-5Q-1267>
Another workaround is to "unset HISTFILE" before setting it. This works even
if HISTFILE isn't already set.
