23.0.60; Crash in face_at_buffer_position

["Lennart Borgman (gmail)" <lennart.borgman@gmail.com>]

I am not sure if this bug report is of any value. I believe it might 
have something to do with that I have made some bad changes to 
syntax-ppss. Anyway, I did not expect Emacs to crash. Here is what I get 
from the debugger:



Program received signal SIGSEGV, Segmentation fault.

The backtrace seems to be very, very long.
