Hi, all,

I run into Segment Fault in:

======

x = 0

for i = 1, 100 do
x = tostring(i)
end

y = "101"

======

And it turns out the JITed code overwrites native stack position at trace head. It can be walked around by set SPS_FIXED to 0.

The JITed code is doing register spill and assuming there is "2 fixed spill slots" (defined by SPS_FIXED). But there seems no "fixed spill slots" in arm64 interpreter implementation. Is it true? Could anyone provide some info of aarch64 frame layout?

Any input will help! Thanks.

Best regards,

Zhongwei
