State-Changed-Why:
Hm, more questions: I tried this testcase on a x86 Linux
box. Without optimization, it takes at a max 14 MB of
memory (3.2.2 prerelease), when watched with "top". With -O3,
this increases to about 22 MB. This does not seem like an
unreasonable increase.
Can you tell us what these numbers are on your machine (i.e.
without and with -O3)?
Thanks
Wolfgang
