broken calc on 21.2.50

broken calc on 21.2.50

[Tak Ota]

In the latest CVS version (21.2.50) the calc package is broken.

M-x calc

' a x ^ 2 + b x + c = 0 RET a S x RET

fails to solve the equation but produces an error message "Variable is
void: 'while".

It works for me. Can you reproduce that with emacs -q? Can you (set
debug-on-error-t) before that error?

Could you M-x toggle-debug-on-error and send a backtrace, please?  I
can't reproduce this.

That is strange.  Yes emacs -q --no-site-file still shows exactly the
same result.

It does not help in this case.  I tried it in vain even before you
asked.  The error is reported from calc package and not from the emacs
lisp interpreter.  I believe the cause of the error is determined by
the following location.

calc.el:2363:		   (calc-record-why "*Variable is void" (nth 1 err)))))

I suppose the issue is in the calc package however the following is
my environment which may not be the majority here.

(set debug-on-error t) of course :-)

Can you try another system?

I tried this on a Windows environment compiled with gcc and get the
same error as Tak. On a GNU/Linux system all works fine. This is maybe
the reason why Colin an Pavel could not reproduce the problem.

My system is GNU Emacs 21.2.50.1 (i386-mingw-nt5.0.2195):

Actually (setq debug-on-error t).

I just fixed one issue in CVS which might have caused this, although I
don't know why this particular symptom would have only popped up on
Windows.

I confirmed that it fixed the reported problem.  Thanks.  I have no
idea either, why this problem was unique to Windoze.
