I expect this to happen if you try to *run* your scripts.  Try just
compiling them, with luac or similar.  This doesn't produce errors:

5 rjek@trite:~ $ cat test.lua
function_A(1, 2, 3)
function_B(4, 5, 6)
6 rjek@trite:~ $ luac -l test.lua

main <test.lua:0,0> (11 instructions, 44 bytes at 0x61a530)
0+ params, 4 slots, 0 upvalues, 0 locals, 8 constants, 0 functions
        1       [1]     GETGLOBAL       0 -1    ; function_A
        2       [1]     LOADK           1 -2    ; 1
        3       [1]     LOADK           2 -3    ; 2
        4       [1]     LOADK           3 -4    ; 3
        5       [1]     CALL            0 4 1
        6       [2]     GETGLOBAL       0 -5    ; function_B
        7       [2]     LOADK           1 -6    ; 4
        8       [2]     LOADK           2 -7    ; 5
        9       [2]     LOADK           3 -8    ; 6
        10      [2]     CALL            0 4 1
        11      [2]     RETURN          0 1

The script compiles without issue.  How are you "syntax checking" your
scripts?
