Why did the linker try to resolve symbols in lopcodes.obj since
presumably  luac.obj is listed before lua.lib?
How are you building luac.exe?

I'm using script based on "etc/luavs.bat" to build Lua under Visual Studio command prompt.
It worked perfectly with all previous versions of Lua.
 
@setlocal
@set MYCOMPILE=cl /nologo /MD /O2 /W3 /c /D_CRT_SECURE_NO_DEPRECATE
@set MYLINK=link /nologo
cd src
%MYCOMPILE% /DLUA_BUILD_AS_DLL l*.c
del lua.obj luac.obj
%MYLINK% /DLL /out:lua54.dll l*.obj
%MYCOMPILE% /DLUA_BUILD_AS_DLL lua.c
%MYLINK% /out:lua.exe lua.obj lua54.lib
%MYCOMPILE% l*.c
del lua.obj linit.obj lbaselib.obj ldblib.obj liolib.obj lmathlib.obj loslib.obj ltablib.obj lstrlib.obj loadlib.obj
%MYLINK% /out:luac.exe *.obj
del *.obj
cd ..
 
Should I set the correct order of .obj files for linker invocation?

What is this order?

You should add lopcodes.obj to the “del” line
