This series of patches has exploded memory usage and I can no longer

As with the Ranger problem exposed by Aldy's patch last September,
something is not freeing memory.
Even on systems where GCC still bootstrap, this excessive memory usage
severely damages GCC compile performance.
Does the change below by any chance make a difference? (It's just
a hunch, I haven't tested it beyond quickly building stage 1 and
running a few tests.)
Hi, Martin
Thanks for the quick response. Yes, I am able to restore bootstrap on
AIX (32 bit) with the change.
Let me finish testing it and if all goes well commit it later tonight.
Now pushed as r12-7043.
Martin
Thanks for the confirmation!
Martin
Thanks, David
