Revolved Hole crash

Rhino (v5.14.522.8390) is repeatedly crashing when I use the Revolved Hole command. It is repeatable which I know helps the debuggers. I created a brand new file with a single square extrusion. The crash occurs when I first select one surface of the extrusion and then the Revolved Hole command. I discovered the bug accidentally when I selected a surface extrusion and meant to select the Round Hole command—which is directly below the Revolved Hole command on the menu.

I couldn’t figure out how to submit a bug report so I hope this helps.

Hi Raymond- thanks, I see that crash/lock-up in V5, but it appears to be fixed in V6.
