A few debugging possibilities spring to mind here.
Try running it under strace with a very large buffer size in (the -b
option). Attach to the hung process in strace or gdb.
Does it also have problems with cygwin snapshots? If not, then we need
to see how you've configured your version of cygwin, what version of gcc
you use, etc.
If this is just a cvs thing (and that isn't really clear) then the old
popular binary search through cvs might be useful to find out what
change caused the problem.
Also, send cygcheck output (as an attachment). I suspect that you may
be using CYGWIN=tty but we don't know what your setup is.
