[2.18] Crash casued by XML view of a large variable
|
I was working on debugging some problems with one of my latest map queries and in order to debug it I had to put the output into variables at different points for me to examine. The particular variable that found this crash for me is 957816 bytes in length. It also caused me to find a number of other bugs with PE display items that will be posted seperately.
Procedure
1. Launch CMud
2. Close Sessions window (ESC)
3. Enter at the command line
| Code: |
| #VAR a "";#VAR b {%repeat("a",300000)};#ALIAS crash {crash} |
4. Open Package Editor (CTRL-G)
5. Click variable 'a' in the tree panel
6. Click the XML tab in the variables view panel
7. Click variable 'b' in the tree panel
8. Click alias 'crash' in the tree panel

I've tested this in v2.25 and cannot get it to fail. Can someone retest this to confirm whether it still happens?
