--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Can you figure out which pass / function uses so much memory? Does using -O1
help? The testcase is positively big, on x86_64 (with -m32) it uses >2GB of
memory even at -O[01], that is, without -g! -fsyntax-only tops at 1.7GB
already
with reduced GC params, otherwise goes close to 2GB (so I mostly blame the C++
FE here).
