Subject: R 1.5.1 (Windows) crashes on plotting density(rnorm(1000)) (PR#1837)
Message-ID: <200207261416.QAA24871@pubhealth.ku.dk>

I am experiencing a reproducible crash from the following statement:

plot(density(rnorm(1000)))

on R 1.5.1 on Windows 2000.

This is a dual-processor machine with 512Mb of RAM.  Please advise if 
further details of hardware/OS are needed.

If rgui.exe is in use, the crash occurs before the plot can be 
displayed.  If rterm.exe is in use, the plot appears, then the error (and 
crash).

A screen capture of the error dialog box  can be viewed/downloaded at

I happen to have Compaq Fortran installed, and therefore a debugger appears 
after the crash.  As I know nothing about systems programming, the debugger 
information (assembler) is meaningless to me, but if it would be useful, I 
can reproduce the crash, save the debugger information, and send it along.

This seems similar to crashes experienced in S-Plus that have been 
attributed to that program's assuming certain behavior on illegal math 
operations, behavior reportedly reset by HP printer drivers.  I do have an 
HP printer installed (hardly avoidable in the PC world).  But that 
observation may be totally irrelevant.

Thanks!
