not loaded to memory

is grass compiled as 32bit or 64bit? 32bit applications can't use all
6GB of memory, only up to about 3GB.

Not really, only diagnostics: the G_malloc error was caused by the
segment library, not r.watershed directly.
Hamish said this is a generic memory problem on MS windows (vista).
I would 1) close grass, 2) reboot windows, 3) make distclean, configure,
make, 4) check if it's now working, 5) if not check if a similar bug has
been already reported, file a new bug if necessary, give up and have a
nice weekend, IOW I'm out of ideas, sorry!
