--- Comment #3 from Matt Hargett <matt at use dot net> 2011-04-20 23:59:45 UTC --- When compiling the example with 4.5.2, memory usage peaks at around 216meg on my Ubuntu 10.10/amd64 machine. With 4.6, it peaks at 3.2gig(!) In the non-reduced test case, it gets up to 7 gig before the machine (which has 9gig total) starts swapping to the point where I have to kill the process. Interestingly (maybe), a GCC 4.6 snapshot from early march doesn't exhibit the problem as badly. It peaks at 'only' 636meg. PS: Sorry for the missing attachment, not sure why attach isn't working upon initial submission...
