Check with new boolean operations (bopcut) leads to unhandled exception in
TKBO.dll and Draw crash.
See stack below.

Problem described in issue is reproduced on current state of OCCT.

The command 'cut' uses old Boolean operations. They are not maintained and will be removed in the future.
Please check if the problem is reproduced with 'bcut'.

Problem is not reproduced then command "bcut" is used instead of "cut".

According MSV comment, command 'cut' should be replaced by 'bcut'.
bcut operation produces valid result since OCCT6.7.0.
Current issue is FIXED. CLOSED.
