I saw this on PowerPC a while back, but the problem was that QEMU's 
application emulation wasn't setting up the registers the same way the kernel 
is.  (QEMU was following the elf spec exactly, and the kernel delegates some 
of the elf spec register layout to the library loader.)

I haven't seen this problem on x86.  I just tried a statically linked hello 
world built from 0.9.29 built with -Os on gcc 4.1.2 and it ran fine.
