tests: cover baecd1cf2685 ("segtree: Fix segfault when restoring a huge interval set")
Test inspired by [1] with both the set and stack size reduced by the
same power of 2, to preserve the (pre-baecd1cf2685) segfault on one
hand, and make the test successfully complete (post-baecd1cf2685) in a
few seconds even on weaker hardware on the other.
(The reason I stopped at 128kB stack size is that with 64kB I was
getting segfaults even with baecd1cf2685 applied.)
