Subject: [Rd] windows/g95 peculiarity
Message-ID: <1253d67a0510081441j66c8ff99u845fbba7f4b2f749@mail.gmail.com>

I'm not looking for an answer here, this is just a report of a
peculiar event I've observed
and can reproduce.

I'm developing a g95 (20050129) compiled package on windows xp pro
using R-2.1.1, and gcc-3.4.2 (mingw special). An older version of the
F95 package compiled and ran without problems. The new version of the
package includes extensive changes in the code.

The package has a test function, rtest(), which sets up a testing
scenario and runs it.

If I try to immediately load the library after starting up R and
running rtest(), the following
occurs:

> library("bpkg")
.onLoad: running R_g95_init
> o = rtest()
Testing cm.estimate...
Using short data set (testing)...
 25500.0000000000 2499.00000000000 11.0000000000000 300.000000000000
...
 5 0.000000000000000
 6 0.000000000000000
Operating system error: Not enough space
Memory allocation failed

(R exits in terminal, or freezes as GUI)

However, if I import a data element the rtest runs fine. I know
rtest() doesn't need the extra data import because it runs without
problems on our OS X version.

> library("bpkg")
.onLoad: running R_g95_init
> data(yij)
> o = rtest()
Testing cm.estimate...
Using short data set (testing)...
 25500.0000000000 2499.00000000000 11.0000000000000 300.000000000000
...
 6 0.000000000000000
Done

>
(R continues to run without problems)

The default rtest runs a short data set because the full test data set
takes about
30 seconds to compute. When I start off by running the full rtest data
set I also
don't have any problems with R.

This package runs without problems on a G4/Tiger OS X mac with R-2.1.1, although
we do compile it with gfortran on that platform.

This is just a report. If anyone has any questions let me know.

Best,

Joel
