[3.19] BUG: Variable corruption
|
I have a couple of variables that seem to be getting corrupted. Whenever a script tries to access one of these variables, I get an access violation error. When I try to view the variable in the package editor, I get another and the editor gets stuck until I close it; Even using #var gives an error when the variable is reached.. It's entirely consistent in my settings, but I have yet to find a way to reproduce it in a fresh one. I'll keep on trying to figure out the issue. It should be noted I had this issue in 3.18d as well.
Once again, I can set you up with my package files if needed.
I was able, apparently, to see the contents of the variable by assigning it a new value on the command line and viewing the results in the script debuger
| Code: |
| 43.539 | k Lanira | [5] Var "defenses" changed from "levitating=1|caloric salve=1|starburst=1|||warmth=1|cloak..." to "" |
It looks like there are multiple blank keys in the variable. Is that supposed to be possible? |

I got all of your crash dumps and couldn't find this problem. The crash dumps were pointing to a line in the code that can't cause a crash, so I have no idea what is going on.
Blank keys in a database variable shouldn't be happening, so something is definitely getting corrupted. Please keep trying to track down the problem, especially since you also had the problem in 3.18. |

Confirmed in 3.19b.
Found a way to replicate the error, but this way involves the package editor.
| Code: |
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
<class name="Test" copy="yes">
<alias name="test" copy="yes">
<value>#99 {
#delkey testvar blah
#addkey testvar blah
}</value>
</alias>
<var name="testvar" copy="yes"/>
</class>
</cmud> |
Import the above, run the alias 'test', open package editor and select the 'testvar' variable, then run the alias 'test' again. You should get the access violation error and the variable will be unusable. |

Yes! I was able to reproduce the crash with the procedure that you gave. I'll see what I can find.

It should be noted that when I first encountered this error, I had not even opened the package editor.

Yeah, it's a memory corruption error, not related to the package editor. Not sure why doing that helps reproduce the problem, but I found it and should be fixed in next update.
