Bash Version: 4.1
Patch Level: 7
Release Status: release

Description:
I tried to write a simple bash script like this:
   #!/bin/bash
   fc -l -2
When I run for the first time it works well, but if I execute again the script I
receive a "Segmentation fault (core dumped)" and the bash die.

Repeat-By:
To reproduce the problem you must create a simple script with the follow 2 
lines:
   #!/bin/bash
   fc -l -2
and then run the script for 2 time. The output is:
   $ . fc.sh
   1000  cd prog/script/
   1001  . fc.sh
   $ . fc.sh
   1001  . fc.sh
   Segmentation fault (core dumped)

Hello Chet!
I had tested your patch in the bash version 4.2, and I didn't found the bug any
more.
All seems works well.


Thanks a lot for the patch.
