It's a similar problem as

  http://groups.google.com/groups?th=e81c8b99f095957f

which is also reproducable with our vi.

vi/vs_refresh.c vs_paint() is calling itself recursively until it runs out of stack and segfaults. In your case, it's "set number", which causes the screen columns to get lowered by 8 characters, but not in a consistent way, so vs_paint() loops endlessly.

It's kind of a non-trivial function, though. "If you change this code, you'd better know what you're doing. It's subtle and quick to anger.", found in a comment there, seems appropriate :)
