of the x11 based games. I'm not going to tag the originals with bsd_44_lite and do this in two stages since it's just not worth it for this collection, and I've got directory renames to deal with that way. Bleah. Submitted by: jkh

Recently hack (1.0.3) crashed with core dumps during some good games.
|
|
The crashes occured in the onbill-routine. After investigating the core
|
|
dump I found that the shopkeeper's bill was still to be paid. Normaly
|
|
if you leave a shop the bill will be cleared and onbill() would not
|
|
check it. But under certain conditions you can leave a shop without
|
|
clearing the bill. The conditions are:
|
|
|
|
1. You have to rob a shop in order to make the shopkeeper
|
|
follow you.
|
|
|
|
2. After leaving the shop being followed by the shopkeeper
|
|
you must return to the shop...
|
|
|
|
3. ...and then leave the unguarded shop again.
|
|
- The shopkeeper mustn't be present!
|
|
|
|
If you climb the stairs to the previous level, chances are that your
|
|
bill now contains much more items than allowed. If so the next call to
|
|
onbill() will dump the core.
|
|
|
|
Following is a context diff to fix the bug. Actually just the last hunk
|
|
does the fix [it deletes two lines which have been inserted in 1.0.3],
|
|
but I think the other fix was intended by the now deleted lines.
