But not on the same source, but different one (insn-recog.c grew because of
that change).

Increasing ulimit from 100 to 110 (10 %!) did not help, increasing it
to 120 helped.

So, we have now hit quite some increase of memory usage with just this single
commit and not just a few bytes...

Yeah, with ulimit you can always pick some limit almost any change might go
over.  As a bug should be only considered if memory usage increases a lot,
daily tiny increases and decreases in memory usage aren't a bug.

The commit you are referring to just hit the nail on the road and gets over
your memory threshold. The blockage insertion is enabled only for
-fno-omit-frame-pointer.

Even if we revert this patch (very unlikely, since it fixes real problem),
memory consumption will go over your threhold as soon as somebody adds a couple
of patterns to the md file.
