Can this test be made simpler? There are only 32M RAM and 128M swap available
on this computer; the test cannot be compiled. It also occasionally triggers
the OOM killer.

no it most likley cannot be made smaller, the whole idea about this test is that it compiles fast and
does not use that much memory. Thanks for pointing out that it uses a large memory, we will be
looking into how to get the memory down.

Compared to 2.95, memory occupation is doubled: 61mb vs 31mb, even at -O0.

It's not surprising this takes more memory than GCC 2.95.3.
There's a very big function in this file, and GCC is now function-at-a-time,
meaning that we build a representation for the entire function in memory, rather
than compiling it one line at a time. That's not to say some improvements could
not be made, but this is a conscious design change. An increase in memory is
inevitable in light of function-at-a-time.

And I can add that there has been progress on this particular testcase: it used
to time-out on some of my low-end machines in 3.3.x, it doesn't on any in 3.4.0pre.
