%%%I am using Blender SVN Rev 45929 Debug Build on a Fedora 16 Linux 64Bit box.

Attached is a Blend file that causes Blender to crash, also is my system-info.txt file and backtrace. It's dynamic paint example file from Jimmy Gunawan.

I got the original file from here, the first 2 files works fine in Blender the 3rd crashes on my box.

%%%Got patch for this but not sure if breaks assumptions about some custom data layers.

Issue is causes by original object which doesn't have loops and for which tessfaces are calculating. Attaching patch which doesn't tries to update face data in such cases, also it was wrong bitflag check.

Assigning to Campbell for verification.%%%

%%%Jimmy asked me to also add:

"Can you inform them that I used LIERO vertex parenting script as well? Meaning there is some kind of old custom connection (vertex parenting related) that I use to generate particle."%%%

%%%I don't think this is really a showstopper, since the crash will only happen in debug mode. It does indicate there's an issue of course, but if it's solved by this simple patch, it's basically just fixing the assert, which shouldn't affect release builds.%%%
