Bug #62227	Index was outside the bounds of the array.

Status:	Can't repeat	Impact on me:	None
Category:	MySQL Workbench: SQL Editor	Severity:	S2 (Serious)
Version:	5.2.34 CE	OS:	Windows (XP, 2002, SP 3)
Assigned to:		CPU Architecture:	Any

Description:
Workbench crashed over the weekend. Restarted Monday morning with two connections that were listed as (autosaved).  Launched the first one, which had one named file tab and four "Query" tabs.  I tried running one of the sql statements in the saved file using Ctrl-Enter but nothing ran. I tried same on several other queries and eventually the tool stopped with a critical error. 

How to repeat:
Use Ctrl-Enter to run a query, before it finishes, ctrl-enter on another query. the system will hang and neither query will complete.  

After restarting workbench the problem cleared. 

Suggested fix:
set up a queue for the queries to run instead of trying to run them all concurrently? display the results in separate Output tabs.

area of workbench that caused the error.

cleared the first error, then this part of workbench failed with same error message.

If you are able to repeat, please right click around the bug icon and select to copy the back trace to the clipboard and paste it here. Thanks.

The process was to (impatiently) ctrl-enter multiple queries from the sql editor window.

Hello Steve.
Are you still able to reproduce this problem?
If that is the case, can you please provide more information about the connection (SSH or TCP/IP, are you using key autentication etc) with are you having problems with? 
Also, can you please tell us the version of MySQL server that you are connecting.

I cannot reproduce the problem this morning. :-( Clicked on multiple queries in the same edit window, and multiple tabs.
