This came in as a new report because of the space between PR and #
Resending it to get it filed correctly.
(BTW: a growth factor of 3-4 is not unexpectable on CSV files since
internal storage of numeric values is in 8-byte doubles.)
> I tried to run the same dataset with R-1.2.3 on Linux, compiled from the
> source tarball. After 7 hours, it was still grinding away and had not
> crashed. I had to kill it. "gtop" was showing it with a real size around 160
> MB, same as the peak on the Windows 2000 environment. This is on the same
> hardware as the Windows run; my machine is dual-booted Windows 2000 and Red
> Hat Linux 7.1. If I get ambitious, I'll see if I can make it fail with a
> smaller dataset and run on Linux with a debug-compiled R binary.
