There seem to be some issues with Windows 7 user accounts
(1)
Windows 7 64bit: User Account
Check.log - failed examples
sh.exe: The application was unable to start correctly (0Xc0000142)
Even when CMD.exe and sh.exe are run under admin privilege. This is however
not consistent. Sh.exe executes every once in a while and example file runs.
(2)
Windows 7 64bit: Admin Account
Check log: All tests OK, BUT the command window closes at the end, even with
option --no-examples/--no-latex.
(3)
Ubuntu:
R CMD check --use-gct --use-valgrind
All tests OK.

The above examples run from within R with valgrind:

On the Windows side, there are clearly issues related to how Rtools function
under different user previleges.
All R related directories have there security setting to allow all user full
access.
On the ubuntu side, I am not sure how to interpret Valgrind results.
R CMD check with valgrind shows no errors
R -d valgrind shows some errors.
Valgrind output file did not include any reference to any of my .c files.
I am not sure how to proceed.
Thanks,
Russ
Hard to say anything if we do not see any details from your package, but
very likely you just had some luck under Ubuntu not to see any crashes...
