Log Message:
make: fix use-after-free in -dp mode (since yesterday)
In a .for loop that contains an unclosed .if directive,
Cond_restore_depth generates an error message. If stack traces are
enabled using the option '-dp', the details of the .for loop are added
to the stack trace, but at that point, the ForLoop had already been
freed. To reproduce:
make-2022.01.09.00.33.57 -r -f unit-tests/directive-for.mk -dp
