Unfortunately, it does not:

    $ make defconfig
    $ make allyespackageconfig

    $ ulimit -s
    8192
    $ make show-vars >/dev/null
    Segmentation fault (core dumped)

    $ ulimit -s 16000
    $ ulimit -s
    16000
    $ make show-vars >/dev/null
    [...]
    Segmentation fault (core dumped)

I guess it works by chance on "small-enough" configurations, but this is
still not guaranteed that it works all the times.

I'd rather have no workaround, than one that is half-functional.

Yes, the above *is* extreme, and a completely degenerate case, yet it
means the issue it still present for "big-enough" configurations (I
haven't tried to find how many packages must be enabled before we reach
the tripping point, but that's not the point).

Yann E. MORIN.
