hmm - weird. i swear this works on big endian, little endian, 64 and 32bit. your
zaurus is 32bit arm - so it should work. have u build with gdb debugging (-g)
can u trace down __deb_fchk and see what exactly sends it turning around and
heading back with an error in hand? i'd like to fix this if we can. the ONLY
thng i can imagine it being is an unaligned memory read/write (the default
zaurus kernel will sigbus on this though - so u'll know pretty fast if it's
that! other kernels for ipaqs etc. enable the kernel "unaligned access fix" -
its dead slow as the kernel traps and does the read of memory for the app - but
it means it works).
other than unaligned accesses arms are just "32bit little endian cpus" a lot
like x86 - just a much cleaner instruction set (its very tasty!) :) (nb - arms
CAN be put into big endian mode too by a kernel - but people choose little
endian as a convention)
