R devel - Nov 2001 - Look, Watson! La.svd & ATLAS

Dear R-devel,

I had attempted to compile r-devel (dated Oct. 31, 2001) on WinNT with link
to ATLAS, with mostly success.  However, when I tried the following, I got a
visit from Dr. Watson:

(Dr. Watson says there's an access violation.)

So far La.svd is the only thing I know of that generates Dr. Watson.

The version info:
         _                           
platform i386-pc-mingw32             
arch     x86                         
os       Win32                       
system   x86, Win32                  
status   Under development (unstable)
major    1                           
minor    4.0                         
year     2001                        
month    10                          
day      31                          
language R                           

Other info:
Hardware: PIII 900MHz w/256mb ram (IBM ThinkPad T22)
ATLAS-3.2.1 compiled from source using cygwin (gcc 2.95.3-5), using default
setting for PIIISSE1
R-devel compiled with mingw gcc 2.95.3-6

Can anyone provide some hint?  Could it be that I just got a bad snapshot of
R-devel?

TIA,
Andy

I was able to run those examples without ill effects on an R-1.4.0
(development) (2001-10-30) with Atlas 3.2.1 on a Linux system (Debian
testing)
