Details:

Hi,

This Makefile segfault for me (make sure to put the space before $i) :
--- 8< ----- SEGFAULT --------------
define x
$(sort $(foreach i,1 2,
 $i))
endef

all:; echo $(strip $(call x))
--- 8< -----------------------------

If you remove the space before $i, or add a \ before the newline above, it's
ok. This is 100% reproducible.

For instance this one is ok:
--- 8< ----- OK --------------------
define x
$(sort $(foreach i,1 2,
$i))
endef

all:; echo $(strip $(call x))
--- 8< -----------------------------

So there's probably a bug somewhere?

Subsidiary question: is the faulty Makefile syntactically correct? (the
absence of \ is ok according to my understanding of 'define', but maybe I'm
wrong).

Regards,
Anthony Mallet
