$$(eval) with SECONDEXPANSION enabled causes make to crash with a
segmentation fault when the expanded variable creates new targets.

The following makefile reproduces the crash:

$ cat Makefile

proj1.exe : proj1.o $$(eval $$(test))
define test
proj1.o : proj1.c
proj1.c: proj1.h

$ make
Segmentation fault
