[ODE] linux amd64 compile error - 0.6-rc1

[Chris M.]

I added a % to push and pop to get this


  asm volatile (
	"mov $0,%%rax\n"
	"push %%rbx\n"
	"cpuid\n"
	"pop %%rbx\n"
	: : : "%rax","%rcx","%rdx","cc","memory");

and it compiled , however the test programs that I have run all crash. 
test_ode gives this

------------------

This is with double precision.
If I rebuild without double precision some things do run and test_ode gives 
this
