HL> Matrix-for-R-2.13@2659 (0.999375-49) has the problem at a
different place:
Are you sure that you really took 0.999375-49 and not its
predecessor ???
The two errors look similiar but different (the previous one was about a
REALSXP), and both are fairly reproducible.
As much as I can be sure, I guess. I overwrote src/library/Recommended and
library/Matrix to be sure.
I haven't been able to reproduce the problem (on 32-bit Linux,
R-2.13.0 RC, after running your code snippet below for a couple
of hours, I got the prompt back, and things continued working..)
and Doug Bates has had a strong suspicion that the error message
below looks like the problem that he fixed just between *-48 and *-49.

Can you give more exact info about the platform ?
fedora 14 x86_64.
export DEFS='-DUSE_TYPE_CHECKING_STRICT -DR_MEMORY_PROFILING'
./configure --enable-memory-profiling --enable-strict-barrier \
--enable-byte-compiled-packages --with-valgrind-instrumentation=2
Matrix-for-R-2.13@2659 was the one I was playing with.
I am currently testing Matrix trunk@2666, since you seems to have put
something relevant in r2661.
finished testing trunk r2666 (0.9996875-0). It takes about 3.5 hours (with
gctorture(TRUE)) to get to:
