If the condition
if (constant_size > 0 && constant_size * nbytes < runtime::kMaxStackAlloca)
is not true, the generated IR cannot work in VM runtime. Please see the detailed explanation here #8274.The bug is not triggering any problem for now, since this condition may be always true in our test. I'm not very sure this is a bug, but we need deeper investigation on this.
