Bug-Description:
|
||
|
|
|
||
|
|
Under certain circumstances, running `fc -l' two times in succession with a
|
||
|
|
relative history offset at the end of the history will result in an incorrect
|
||
|
|
calculation of the last history entry and a seg fault.

||
|
|
|
||
|
|
Patch (apply with `patch -p0'):
