Hello!

I have observed a curious problem with the Windows version of R.
> version
         _
platform Windows
arch     x86
os       Win32
system   x86, Win32
status
major    1
minor    1.1
year     2000
month    August
day      15
language R
> win.version()
[1] "Windows NT 4.0 (build 1381) Service Pack 5"

When I mistype an argument in a function call (like in the example below), Rgui
crashes with the message:
The instruction at "0x025571b8" uses the memory address "0x00000008". The memory
 can't be "read". (This is my translation from French, but I guess it's
something like that in English.)

Example:
> ls(poq=3)
Normally, one should get a message saying:
Error in ls(poq = 3) : unused argument(s) (poq ...)

In my etc/Rprofile file I have added the following line:
options(error=quote(dump.frames()))

When I comment this line out, Rgui works OK (i.e. I get the message "Error in
ls(poq = 3) : unused argument(s) (poq ...)").

This happens for any other typo that should normally cause the message "unused
argument(s)", like "matrix(1:15, nrow=5, byrox=TRUE)", or anything else.

The same happens with Rterm, except that you see the error message before Rterm
dies, and the message is little bit different:
The instruction at "0x02556678" uses the memory address "0xec83e591". The memory
 can't be "read".

It happens on both my desktop and my laptop, but since both are running the same
 OS version (NT4 SP5), it's not so surprising.

Also, I have the same behaviour with the previous version of R
> version
         _
platform Windows
arch     x86
os       Win32
system   x86, Win32
status
major    1
minor    1.0
year     2000
month    June
day      15
language R


Did I do anything wrong, or is it a problem with R.dll?

It is not a big problem, but I just wanted let you know about it.

Best regards

Zivan
