[Message part 1 (text/plain, inline)]

Hi,

when opening the attached TeX file (stripped down to the lines that cause the crash), my Emacs segfaults. Compiled from HEAD this morning 1000 CEST, although I have this problem for two weeks now.  Forgot the backtrace in my previous message.

Program received signal SIGSEGV, Segmentation fault.
