OpenSCAD stopped working for me on designs that previously rendered fine. After testing I found out that any precision greater than $fn=29 causes the program to crash with an error message reading openscad.exe has stopped working. I am need to print parts with precision of at least $fn>100.

I have uninstalled and reinstalled the program several times and haven't been able to fix the problem. I have watched the CPU during the calculations and it never reaches more than 35%.

Does anyone have any suggestions as to how to fix this problem? I also have not changed computers or even the code. Thanks!

I am using Windows 32 bit, Version 2013.06. The default version.

I've been getting this too. Exactly same symptoms. –  Cylindric Dec 16 '13 at 9:58
    
Here is the issue on GitHub. github.com/openscad/openscad/issues/428 OpenSCAD is unusable in Windows 8 right now, so I'm using it in Linux as a workaround. The $fn threshold that causes a crash seems to vary with model complexity. The problem started for me after updating to Windows 8.1 (x64). –  jcdoll Dec 29 '13 at 22:29
