[bug #45728] .VARIABLES not updated after undefine

[anonymous]

Follow-up Comment #1, bug #45728 (project make):

I think the problem is a bit larger than what is exhibited here.

I started with the following script:

#!/bin/bash
# 
gmake --version; 
exec gmake --warn-undefined-variables -f "$0" "$@"

MY_foo:=foo
undefine MY_foo
MY_bar:=bar
$(warning MY variables: $(filter MY_%,${.VARIABLES}))
$(foreach x,$(filter MY_%,${.VARIABLES}),$(eval undefine ${x}))
MY_baz:=baz
$(warning MY Variables: $(filter MY_%,${.VARIABLES}))

all: ; @true




If I run that script, I get output on par with the originally submitted bug --
though it should be noted that it at least appears to work fine unless you use
$(foreach).

If I add an evaluation of .VARIABLES between lines 6 & 7 (copy/paste one of
the $(warning) lines) I get different (also buggy) behavior.  If I put the
$(warning) line in a variable and evaluate that, I get other buggy behavior.
