`unset TZ' is the simplest test case that causes a segmentation fault
on my system.
The culprit appears to be the chkexport function introduced in patch
bash42-005 . From the backtrace , I gather it should probably
check that find_variable returns a non-NULL value. Changing the line
after the find_variable call to read "if (v && exported_p (v))" fixes
the issue for me.
I've sent a bug report to bug-bash at gnu.org using the neat bashbug command. :p
