Current git master works for me on that test program without your patch:
cam-vm-266:maverick:qemu$ ./arm-linux-user/qemu-arm ~/Desktop/mvns_imm.exe 
cam-vm-266:maverick:qemu$ echo $?
0

(I tested on qemu-0.14 just to confirm that I'm running the test program
correctly, and that indeed fails as I would expect it to, exiting with
status 255.)

Which qemu version have you been testing with?
