Hi, I'm having trouble opening a large netcdf file (2.45 GB) with the
following code on R 3.0.3 64 bit

require('ncdf')
nc <- open.ncdf('C:/testsMCH/test/wrfout_d02_2014-06-09_00%3A00%3A00')
get.var.ncdf(nc, 'T2', start=c(1, 1, 1), count=c(-1, -1, -1))

I get this error:
Assertion failed!

Program: C:\Program Files\RStudio\bin\x64\rsession.exe
File: posixio.c, Line 417

Expression: offset >= 0

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.


In R 32 bit there are no problems.

It is the same problem as reported here:
http://r.789695.n4.nabble.com/Problems-with-Raster-and-clim-pact-packages-with-large-netcdf-files-2-7G-in-x64-bit-R-td4119638.html#a4691956

Does anyone have any clue as to why this may be?
I can upload the file on an FTP server but it'll take me a while.

Thanks in advance!
Pablo
