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.
