I mean, this code may work in improper way if ASAN allocates only 0x20 bytes on
the stack:
```
138d: bf 80 03 00 00 mov $0x380,%edi
1392: e8 39 fd ff ff call 10d0 <__asan_stack_malloc_4@plt>
1397: 48 85 c0 test %rax,%rax
139a: 0f 84 88 fe ff ff je 1228
<_Z13gate_x1_curvePfPKfPKN3dsp11gate_knee_tEm+0x3f>
13a0: 48 89 c3 mov %rax,%rbx
13a3: e9 80 fe ff ff jmp 1228
<_Z13gate_x1_curvePfPKfPKN3dsp11gate_knee_tEm+0x3f>
13a8: 48 c7 03 0e 36 e0 45 movq $0x45e0360e,(%rbx)
13af: 48 be f5 f5 f5 f5 f5 movabs $0xf5f5f5f5f5f5f5f5,%rsi
```
