Here's the different chains I've tested with:

Host 1: Athlon XP 2200, debian unstable, 2.6.0-test6 
Binary gcc dist, available from: http://www.openzaurus.org/official/toolchain/
2.95 from here works, 3.3.1 and 3.3.2 fail. 

3.3.2 info from gcc -v:

Thread model: posix
gcc version 3.3.2
 /opt/cross/lib/gcc-lib/arm-linux/3.3.2/cc1 -quiet -v -D__GNUC__=3 -

GNU C version 3.3.2 (arm-linux)
        compiled by GNU C version 2.96 20000731 (Red Hat Linux 7.3 2.96-113).
GGC heuristics: --param ggc-min-expand=64 --param ggc-min-heapsize=64308

Host 2: Dual Opteron x86_64, Suse 9.0, 2.4.21-193 SMP kernel
Running the 32bit binaries noted above gives the same. 
However, I have a 3.3.2 x86_64->arm-linux tool chain built, gcc -v output:

The 3.4 codesourcery toolchain is x86_64->arm-linux too, gcc -v output:

Mark: Do you have a binary tgz of a working i386 toolchain I could test with ?
