No, of course shouldn't -O2 be hardcorded, but the idea behind that was,
that w3m core dumpes, when compiled _without_ -O2 (at least on my
machines and some other machines here). Though the "-O2-Trick" seems not
to work everywhere.
The real problem is likely to be in boehm-gc.=20

"New(GeneralList)" doesn't look too bad for me (though I'm not really a
C coder)
Maybe someone could look more into it? (compile boehm-gc with "-g" or
contact the authors or something)? Maybe it's even a gcc/libc-problem?
Thanks,
Markus
