Can you give me something that will allow me to reproduce the problem
more easily? I can't reproduce it with something like this:
foo()
{
echo "bar()"$'\n'"{ echo in bar;"$'\n'"}"
echo echo one
echo echo two
echo echo three
echo echo inside
echo type bar
echo bar
}
source <(foo)
echo outside
type bar
echo $?
Does it take a script of a certain size to trigger the problem? If the
problem is as you describe it should not work anywhere.
I happen to be using exactly the same release of MacOS X and kernel version
you are.
