(1) Does it happen *without* the patches?
(2) The canonical way to investigate is to
(a) figure out which file is being processed and rerun R with
output to the terminal. I.e.
export SRCDIR=../R/tests # must be set, value depends on build setup
bin/R --vanilla < $SRCDIR/reg-tests-1.R
This avoids buffering and so the last few lines should tell
you approximately where things go wrong.
You might want to cut the file down a bit, but in this case it
is probably not necessary.
(b) Run R under the debugger
bin/R -d gdb
run --vanilla < $SRCDIR/reg-tests-1.R
when it hangs, try hitting control-C and do a "bt" (backtrace)
command in gdb. You can then poke around in the stack and see
if you can spot the problem. Or get back to us with some new
