This is a bug, which has been fixed for the next release:
https://savannah.gnu.org/bugs/?61463
In the meantime it will work to separate the export from the private,
like this:
FOR_FOO := global
foo: private export FOR_FOO = $(p_FOO)
foo: private p_FOO := 1
foo: bar baz
foo bar baz: ; @echo $@: $$FOR_FOO
(the "private" on the first foo: line doesn't have the desired effect
until the above bug is fixed but I left it there anyway).
Note it's of course critically important to use "=" in the export
assignment, not ":=".
