Do I read the backtrace correctly to indicate that Fabs was called with an argument that is a symbol, not a number? If so, how could it possibly evade the CHECK_NUMBER_OR_FLOAT test just before XFLOAT? That sounds similar to a problem Cygwin users had, whereby some system code invoked by a signal handler or another thread (and which thus interrupted Emacs between the test and the use of the value) didn't preserve registers correctly. Is there any other explanation?
