Subject: Problem booting 2.6.32 built with gcc 3.3.5

Hi list,

I am unable to boot a 2.6.32 vanilla kernel when it is built with a toolchain based off gcc 3.3.5.  When building this kernel on gcc 4.2.4 it boots happily.  The config file remains unchanged.  I can supply this config file if anyone thinks it would be useful.

The problem seems to be related to the decompress code in arch/x86/boot/compressed/misc.c.  When booting the kernel built with gcc 3.3.5 I see a message:

Destination address too large -- System halted

I've tried this kernel on virtual box and on physical hardware with the same results.  The gcc 3.3.5 chain is able to properly build earlier kernels, 2.6.16.* specifically.

Has anything changed with regard to recommended compilers on newer kernels?  I assume most people build there kernels with gcc 4, but is gcc 3 still tested?

Any help gratefully appreciated.  I'm not on the list, so please keep me in the CC.
