Hi,
after upgrading from 2014-11-09 to 2014-12-04 OpenSCAD has begun to crash my
machine. Everything locks up and I need to do a hard power off to restart
it. I can't see any pattern when it happens. Perhaps when saving file, og
when previewing. (I rarely render, so its not that).

When the maching starts up again I've experienced a few times that the .scad
file has been corrupted. It only contains one line, and that line is just a
lot of NUL values. See screenshot.

I saw someone else mentioning OpenSCAD freezeing their machine as well, but
can't find that thread.

The other report suggested the auto-reload feature was loading the file
before NP++ (IIRC anyway an external editor) had finished saving it.

Are you using Auto-reload?

The entire computer locks up, as in you can't even move the mouse?

Unless you are using Windows 98 :) a lock up of the entire computer is
usually a driver problem. In this case, it "must" be the graphics driver, as
OpenSCAD is a graphics program.

Yes, the entire machine freezes. Its as close to a bluescreen you can come
without it actually flipping over to the bluescreen.

Yes, I totally agree that the only thing that can cause this is a driver -
but I'm already using the newest version of the AMD driver. My money is
rather on OpenSCAD telling the videodriver to do something which is just way
off, and this causes the crash.

I'm running on a Samsung laptop which has two videocards. Both an Intel HD
Graphics 4000 and a AMD Radeon R9 M270X. When I use "TechPowerUp GPU-Z
0.8.0" to look at the processorpower of the two it seems like the AMDs GPU
is working really hard when OpenSCAD is open. My feeling is that OpenSCAD
uses the graphicscard in a inefficient way.

And, no, I'm not using the Auto Reload feature.

Post Windows 98 it doesn't work like that. Windows actually grew up and
started to become an operating system. If it locks your box even by
telling it to do silly things then its a graphics driver/hardware bug
(and if its a hardware bug its a driver bug that it doesn't work around
the hardware bug ;-))

For F5 renders of certain curved surfaces I see similar problems in Linux
with a really old radeon card but not with Intel graphics. I'm pretty
sure its a driver bug in both cases therefore.

is working really hard when OpenSCAD is open. My feeling is that OpenSCAD

The F5 render does, but inefficient and crashing are quite different
things.

Note that OpenSCAD saves backup files in my documents\openscad\backups.
