Creo Parametric 7.0.2.0 crashes using config option "sketcher_diagonal_constr Yes"

Hi everyone, 

Creo parametric - Release 7.0.2.0 crashes prematurely if config option "sketcher_diagonal_constr yes" is set and when you use the "Replace" function in the sketcher. To reproduce this issue do the following:

• Open Creo parametric - Release 7.0.2.0 without any configurations but only with opiton "sketcher_diagonal_constr yes". All other options are now default!
• Create a new part without standard part. Use option "Empty" to create that part.
• In new part create standard datum planes and create first geometry using protrusion on one of the standard datum planes
• Sketch a rectangle and leave Sketch, finish this feature
• Enter the sketch of this feature again using "Redefine" and draw an arc/spline/additional lines with the intention to use the "Replace" function from up popping Mini Menue in the sketcher. While sketching watch the snapping functionality trying/offering where to snap showing this with appearing/disappearing dotted lines.
• Select an existing, old line and click "Replace" from the up popping Mini Menue. Then select the new line/arc/spline to keep. A confirm window with options Yes/No appears. Selecting "Yes" Creo crashes.
• If it doesn't crash leave the sketcher and repeat the "Redefine" several times like described above. After some Replace actions it will crash reproduceable. 

How ever, setting the config option "sketcher_diagonal_constr NO" the version 7.0.2.0 runs fine.

@unknown: how to open a case for a Creo version that is brandnew? I did not find a way to support you figuring out this issue. Now just read it in the newspaper tomorrow... 😉
