Following this idea I do the following test:

on a b2k unstable debian install with toolchain pkg:

ii  gcc            3.2.2-0        The GNU C compiler.
ii  gcc-3.0        3.0.4-14       The GNU C compiler
ii  gcc-3.0-base   3.0.4-14       The GNU Compiler Collection (base package)
ii  gcc-3.2        3.2.2-0pre5    The GNU C compiler
ii  gcc-3.2-base   3.2.2-0pre5    The GNU Compiler Collection (base package)
ii  gcc-snapshot   20030118-1     A SNAPSHOT of the The GNU Compiler Collectio
ii  libc6          2.3.1-10       GNU C Library: Shared libraries and Timezone
ii  libc6-dev      2.3.1-10       GNU C Library: Development Libraries and
Hea
ii  binutils       2.13.90.0.16-1 The GNU assembler, linker and binary utiliti
ii  binutils-dev   2.13.90.0.16-1 The GNU binary utilities (BFD development
fi

I build first kernel-2.4.20-pa22 with default gcc (ie gcc-3.2); without surprise
it crashed on the first incomming ip connection.

I then 'make distclean', replaced gcc by gcc-3.0 into Makefile and rebuild
so the same sources with the same .config. The result is an operational kernel.

Trust me, in this test the only variable is gcc release. Does it help?

That said, always in the continuity of this idea, I also notice that ld is
used to build some kernel parts. Is it  possible (even manually just for
test) to use gcc in place of ld? (if yes, howto?)

hth,
    Joel
