I have received the following error for my package oro.nifti under "CRAN checks" for r-devel-linux-ix86; i.e.,

Error in read.nifti.content(fname, gzipped = TRUE, verbose = verbose, : -- extension size (esize) has overshot voxel offset -- Calls: readNIfTI -> read.nifti.content Execution halted Please draw your attention to the two lines annotated above. The line of code that "looks a bit odd" above is cat(" writing niftiExtension(s) at byte =", seek(fid), fill=TRUE) ...where fid is a call to file()... and this large number is causing the subsequent read function to fail. My questions are: - Why would this error occur in 32-bit linux only for R 2.12.0? - How can I test any fixes to this error given I am not running R in 32-bit linux? Any suggestions would be welcome.
