christos 8e2797bc1e PR/11283: Hubert Feyrer: random memory corruption executing commands:
Fix from FreeBSD:

    growstackblock() sometimes relocates a stack_block considered empty
    without properly relocating stack marks referencing that block.
    The first call to popstackmark() with the unrelocated stack mark
    as argument then causes sh to abort.

    Relocating the relevant stack marks seems to solve this problem.

    The patch changes the semantics of popstackmark() somewhat.  It can
    only be called once after a call to setstackmark(), thus cmdloop() in
    main.c needs an extra call to setstackmark().

cgd edc0ef345c Fix growstackblock() 'newlen' calculations:
(1) it needs to be ALIGNed for both halves of the 'if,' and
	(2) if you're going to claim that you now have ALIGN(newlen)
	    bytes left, you should have actually allocated
	    ALIGN(newlen), rather than just 'newlen' bytes.
