The test program works fine with current git master, so I think we have
fixed this bug at some point in the last two years.

linux-user: x86_64 target fails to call sys_futex()
Status in QEMU:
I'm building the latest QEMU
(06b4f00d53637f2c16a62c2cbaa30bffb045cf88) on ARM to run some x86_64
executables in user mode. This is my configuration:
The following program is used for testing:
I compile the test program in Debian-7.5-amd64 like this:
gcc -o test `pkg-config --cflags glib-2.0` test.c `pkg-config --static
--libs glib-2.0` -static
and launch the program on ARM with
The test crashes with the following message:
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
The output of `strace qemu-x86_64 test` is here:
It seems that the error is caused by the failure of the futex syscall.
qemu-i386 could launch the 32-bit test perfectly, the problem only
happens on a x86_64 target.
