You're comparing 2.10.0 on Windows with 2.11.0 on Linux.
Have you tried 2.11.0 on Windows? => same result as on Linux.
Indeed, this is new functionality added to R-devel (5 Jan). Indexing an
n-dim array with an n-column matrix used to only be supported when the
matrix contained integers. Character matrices are now supported to map
to dimnames of the array. Here's the NEWS entry:
o n-dimensional arrays with dimension names can now be indexed
by an n-column character matrix. The indices are matched
against the dimension names. NA indices are propagated to the
result. Unmatched values and "" are not allowed and result in
an error.
