Does it help to upgrade to binutils According to this...

the fix is to use binutils newer than 2.12.90. NetBSD 1.6 is shipping
with binutils 2.11.2. They also say that -fno-rename-registers may not
work around the bug in all cases.

I'll look into updating the binutils package, and making the gcc3
package use them. Assuming that's the problem, this isn't an issue for
the base toolchain at all.
