Hello, On my side, I can see a huge increase in memory use (up to at least 350GB in make check) by GCC since this commit. (and the Compute Farm admins have started to kill my jobs because they consume too much memory ;-) I can see this on several ARM and AArch64 configurations, but not on armeb, aarch64-bare and arm* when restricting to armv5t.
