Bad value from read-from-string

Bad value from read-from-string

[Juanma Barranquero]

On HEAD:

emacs -q --no-site-file
M-x ielm
1 [enter]

=> Args out of range: "1", 7, 1

Only happens with the first expression evaluated. It is caused by the
value returned by read-from-string.

Should be fixed now; please let me know if not.

The bug was caused by the order of evaluation of function arguments
inside Fread_from_string, and my code depended on it being
left-to-right.  GCC always uses left-to-right, so I'm assuming this bug
was revealed because you use the Windows compiler.

Yes, now it works. Thanks.

Yes, I was compiling with MSVC 6.0.
