The only relevant change I can find is that CVS will now use mmap() (if
available) to map the RCS file into memory and access it directly rather
than reading it in using normal I/O routines; the most likely problem is
that your system has a defective mmap() routine.  Check your generated
config.h file for HAVE_MMAP.  You'll almost certainly find that it's
#define'd to 1; comment out that definition and rebuild CVS.  If that
eliminates the errors, you know that your mmap() is broken -- please
check with your system vendor for fixes.
