[hotrhino]

i useluajit in my project and i found asan3 can't detect the stack-buffer probs right. It report my program stack-buffer-underflow/overflow while it's not.

orgin files:
lua_test.tar.gz
lj_debug.txt

stacktrace:
==4342==ERROR: AddressSanitizer: stack-buffer-underflow on address 0x7ffc1b1043d8 at pc 0x7fc3d67e99d7 bp 0x7ffc1b1041d0 sp 0x7ffc1b103978
