Comment 2 for bug 714921

Oh, and of course arm is 32-bit, so raising the ulimit above 4GiB will have no effect whatsoever. Heh. So perhaps this is why it works ok in the cross-compiler, since I'm cross-compiling from amd64.

Still, the cross-build required only 3250MiB, and snapshots of cc1 usage natively never show it exceeding 1.7GiB. Is there some in-kernel limit on the maximum per-process memory that we're hitting?

Is this behavior - allocating another 1MiB for every 700KiB written to disk - expected from gcc, or is this a buggy use of a buffer?
