I have the exact same problem with Civil3D 2012 (Service Pack 1). Is there a solution to this problem yet?
This has been logged as defect 1436364, and C3D 2013 includes the fix. For now the workaround is as the original poster said in his post...disable the node osnap to avoid the crash.
Civil 3D 2012 Update 2 includes a fix for DID 1436364 mentioned above. Hope that helps.
I'm getting this same exact problem with split (multiple) profile views in 2019, 2021, 2022 Civil 3D. All updates installed, windows, dell, and autodesk. I've even deleted the profiles and started over, to no avail. When I copy a piece of text into the views with osnaps on it crashes- I even turned off the NODE osnap but no change. I've submitted about 100 error reports.
Additionally, I'm projecting plan view feature lines into the split profile views- just noticed that when I explode the projected profile view feature line it doesn't crash when I copy a piece of text to it with osnaps on.
