Bug #77895	MySQL Workbench Crashes when Trying to Open Connection

Category:	MySQL Workbench	Severity:	S1 (Critical)
Version:	6.3.3.0 build 592	OS:	Windows (Windows 10)
Assigned to:		CPU Architecture:	Any

Description:
I just upgraded to Windows 10 and when I try to connect to any of my instances, the program crashes. Rebooting the machine and uninstalling/reinstalling workbench seems to have no effect. I'm sure it's probably a Windows 10 thing, but I wanted to bring it to your attention.

How to repeat:
1) Install Windows 10.
2) Open MySQL Workbench.
3) Try to connect to any of your DBs.
4) Watch the hilarity ensue.
5) Lather, rinse, repeat.

Suggested fix:
I have no idea.

Here is the stacktrace from the crash...

Sorry. I found the duplicate bug with the corrected DLL.

That solved the problem. This can be closed.
