[JSFX] sprintf() messing with its arguments

[[REAPER v6.82 - Mac OS Ventura 13.3 on Mac Studio]]
This simple code gives incorrect results. After:

Code:

function xed(str, val)
(
    sprintf(str, "%d", val);
    str;
);

sprintf(#res1, "Ex-1:  %s  %s", xed(#A1, 345), xed(#A2, 678));

xed(#A3, 345);
xed(#A4, 678);

sprintf(#res2, "Ex-2:  %s  %s", #A3, #A4);

String #res1 is "Ex-1: 678 678" (incorrect) while #res2 is "Ex-2: 345 678" (correct).

thanks! from what I can tell this only affects the arm64 version of EEL2/JSFX, fixing!

FWIW, fix confirmed (on Apple M1).

(narrator: it also affected arm32 and a hypothetical PPC build)
