Blender Version
Broken: version 2.71 (sub 0), branch b'master', commit date b'2014-06-25' b'18:36', hash b'9337574', b'Release'

              build date: b'2014-06-25', b'22:33:12'
          version 2.70a (unknown details)

Worked: (optional)

Short description of error
System crashes/hangs when I change the font from the default, specify values Geometry -> Modification and Bevel, and rotate the view (using middle mouse button).
Crash is not instant, but it always occurs. Though I'm uncertain whether or not it will be widely reproducible, if it is a problem on more than just my machine it is a pretty bad problem.
Converting the text to mesh appears to avoid the problem.

I was not able to reproduce the problem using version 2.71, 64-bit OS X
After the problem first occurred, I updated my video card driver to the latest version. The problem did not change.

Exact steps for others to reproduce the error

Steps are based on this tutorial: https://www.youtube.com/watch?v=ipYiwUmBfs8

Create Text object
Change font (crash has occurred with all fonts that I've tried except the default)
Alter values for Object Data -> Geometry -> Modification and Bevel
Use middle mouse button to rotate view about the text.

File included it setup to point just before crash would normally occur on my system.
All one needs to do now is rotate the view using the middle mouse button.
As I mentioned before, it may not be instant (and for others it may not happen at all), but for me it happens 100% of the time

b'9337574', b'Release' ``` build date: b'2014-06-25', b'22:33:12' version 2.70a (unknown details) ``` Worked: (optional) **Short description of error** System crashes/hangs when I change the font from the default, specify values Geometry -> Modification and Bevel, and rotate the view (using middle mouse button). Crash is not instant, but it always occurs. Though I'm uncertain whether or not it will be widely reproducible, if it is a problem on more than just my machine it is a pretty bad problem. Converting the text to mesh appears to avoid the problem. I was not able to reproduce the problem using version 2.71, 64-bit OS X After the problem first occurred, I updated my video card driver to the latest version. The problem did not change. **Exact steps for others to reproduce the error** Steps are based on this tutorial: https://www.youtube.com/watch?v=ipYiwUmBfs8 Create Text object Change font (crash has occurred with all fonts that I've tried except the default) Alter values for Object Data -> Geometry -> Modification and Bevel Use middle mouse button to rotate view about the text. File included it setup to point just before crash would normally occur on my system. All one needs to do now is rotate the view using the middle mouse button. As I mentioned before, it may not be instant (and for others it may not happen at all), but for me it happens 100% of the time [FontChange_CrashOnViewRotation.zip](https://archive.blender.org/developer/F96051/FontChange_CrashOnViewRotation.zip)

The file included references BEBAS___.TTF, I downloaded from here: http://www.dafont.com/bebas.font

But couldn't redo the bug, rotating the view works fine.

That was the font used in the tutorial, but for me the problem doesn't seem to be limited to this font because the problem occurred with several other common fonts. I was afraid it wouldn't be reproducible because I couldn't find anyone else with the same problem.

Doesn't happen here as well. Please try using opengl32.dll from ftp://ftp.blender.org/sergey/softwaregl/ I remember some simila issues were caused by a buggy video driver. Put this dll next to blender.exe and give it a try. This will swtch blender to fully software opengl mode, eliminating possible interference with buggy drivers.

Thanks for the suggestion Sergey,

Speaking tentatively, this may have resolved the issue. Have only done superficial test, but so far no crash. Will update if this changes.

Just a guess but isn't it possible that the freetype library sometimes passes weird vector data? Usually 2D font rendering is very tolerant about self-intersecting curves, and font creators are not afraid to use it. Perhaps the truetype fonts are just not always Blender-compliant.
