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?
