Hi,

Thanks for pointing that out. I double checked my programs and yes, they seem 
to be 64bit ones. I assumed they were because my toolchain was a 
sparc64-unknown-linux-gnu, but I hadn't verified the generated elf files.

% make
sparc64-unknown-linux-gnu-gcc -Wall -W -g -O2   -c -o ctest.o ctest.c
sparc64-unknown-linux-gnu-gcc -static  ctest.o   -o ctest
% file ctest
ctest: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), for GNU/Linux 
2.4.1, statically linked, not stripped
% ~/src/c/qemu/sparc/sparc64-linux-user/qemu-sparc64 ./ctest
Segmentation fault

I'll retry with a fresh CVS build.

Best regards
