Description
I'm always seeing the following 2 test failures due to crashes in qemu-arm when running Mike's test suite in the openresty/luajit2-test-suite github repo with a cross-compiled build of LuaJIT (both the official v2.1 branch and our v2.1-agentzh branch):
Failed test when running /home/agentzh/git/luajit2-test-suite/arm-luajit wbarrier_jit.lua 1: 139
...
Failed test when running /home/agentzh/git/luajit2-test-suite/arm-luajit parse_andor.lua 1: 139
...
2 tests failed.
Not sure if they are reproducible on real ARMv7hf hardware.

Research direction
Start by reproducing the qemu-arm crashes in wbarrier_jit.lua and parse_andor.lua using the cross-compiled LuaJIT build described in the report. Compare the failures with execution on real ARMv7hf hardware if available, then identify the cause; done means both tests complete without segmentation faults.
