We're not running 4.3 here, but I think I may have found and fixed the
same bug.  The Achilles heel is that .h files which #include each other
with a  #ifndef to break the chain cause isintdep to recurse and dump
core.  This will show up as an enormous repetitive backtrace when
you look at it with dbx or adb.  I have a patch to fix this which
borrows the r->mark field to determine if we've been by already, and
takes care not to recurse unless we know it's 0.   I'll send it via
mail to anyone who has a licence for nmake.
