Any guesses what's going on with this?

Is this a coincident surface problem or something? Or does CSG merge 
always work this way?

Lookslike coincident surface is likely.  Just difference a plane to clip the
front and back of the letters.

I wrote a little macro that randomly translate an object to prevent
coincident problems. It only moves the object by +-.0001 but that does the
trick. Once you write the macro just put it in every object being used.

bit of both. Merge means union and remove all internal surfaces. You've got
2 surfaces coincident, so the merge thought they were both internal and
removed both. Just offset one by a little. +-0.0001 works fine.
