Hm, I see some odd numbers in *igc roots*:

bc-stack                       ambig               1         4194304
pure                           ambig               1        41333328

40 MB pure space :-).  It looks like PURESIZE isn't the number of words
but the number of bytes.  Or so it seems in alloc.c:

EMACS_INT pure[(PURESIZE + sizeof (EMACS_INT) - 1) / sizeof (EMACS_INT)] = {1,};

4 MB bc-stack also seems a lot.  But it's less obviously wrong.

It helps to sometimes look at basic things :-)
