Hi All I am getting following error when I try to dump the machine code for test/tnew.lua
$ ./luajit -jon -jdump=m ../test/tnew.lua ---- TRACE 1 start tnew.lua:1 ---- TRACE 1 mcode 316 VM handler failed: ./jit/dis_arm.lua:439: attempt to call upvalue 'concat' (a nil value)
$ ./luajit -jon -jdump=m ../test/tnew.lua ---- TRACE 1 start tnew.lua:1 ---- TRACE 1 mcode 384 VM handler failed: ./jit/dis_arm64.lua:755: attempt to call upvalue 'concat' (a nil value)
The error is seen on ARM64 and ARM32 but not on x64. I am having tough time to debug the asm_tbar function for failure of test_tnew. Any suggestion is welcome.

Ok. Got the response on another list. The name "table" in the test case is causing problem.
The test case needs to be updated to not use keyword "table" as a name for table. Abhishek Dikshit

Thanks for your update. But why this doesn't fail on x64?

That is because x64 doesn't use table in its VM.
