The earlier troubles seemed to be related to linking, so my memories about
the binutils-2.11/ppc-eabi issue didn't suit to this case...
You did find a bug and a unworking target more in gcc-3.0 ...

I have only the gcc-3.0 and 3.0.1 prereleases (the snapshots), but the
gcc-20010618 snapshots gave just the same result. The error and the resulted
assembly I got was:
-------- the error got from build -----------

So the '_ZTISt9bad_alloc' is an address in another section. An earlier
.long _ZTISt9bad_alloc
was approved, but what is wrong in the '.4byte' and why the address given
with it cannot be relocated goes beyond my knowledge...

Lets hope the previous code sample lets some PPC-guru to get a clue...
BTW, I did a check with the gcc-3.0 prerelease perhaps two weeks ago
and got the following results with six quite random embedded targets:
Target Does it work in gcc-3.0
----------------------------------------------
fr30-elf No, the build crashes
m32r-elf No, the build crashes
mn10200-elf No, the build crashes
mn10300-elf Yes, the build succeeds
i386-elf Yes, the build succeeds
v850-elf No, the build crashes
Only 2 from the 6 already working (2 from 7 now) didn't hint the gcc-3.0
to appear 'Really soon now', but it appeared anyhow... All the crashes
were because of internal errors. I will probably try these again and
will also try some other targets too, but with the gcc-3.0.1 snapshots.
Getting the gcc-3.0 release from the gcc-3.0 prereleases or from the odd
'gcc-3.0-20010527' release isn't supported via diffs at all and so keeps
the snapshots-builders and the release-builders as separate groups... Why
the possibility to get the 3.0 release from the gcc-20010611-snapshots is
not offered is one of those things I don't understand.
Cheers, Kai
PS. I got the m32r-elf result already, the build crashed with the following
error in libstdc++-v3 :

Not so good code generation for Mitsubishis either...
