The slow performance of serializing to a raw vector on Windows is an
issue that has appeared in this list before. It appears to be due to
the frequent use of realloc from the resize_buffer method in
serialize.c.
I suggest a more granular, but still incremental, re-allocation
Dear R-devel readers:
I am really stuck trying resolving an issue with the use of the
Matrix in one of my packages, irlba, with R-2.14.0. When I use
crossprod with at least one sparse argument in the packaged code I

Although it does not solve the issue, the INF result is due to the
MinGW gcc math library on 64-bit Windows that R links to. One can
easily see this by compiling just machar.c and checking pow and sqrt
on xmax.
Note that on any platform the results are likely to be quite different
between pow and
