[Libguestfs] index-parse.c:1256:6: error: assuming pointer wraparound does not occur when comparing P +- C1 with P +- C2 [-Werror=strict-overflow]

No idea why this happens: index-parse.y: In function 'yyparse': index-parse.c:1256:6: error: assuming pointer wraparound does not occur when comparing P +- C1 with P +- C2 [-Werror=strict-overflow] if (yyss + yystacksize - 1 <= yyssp) ^ It only happens on one machine, and not on any others, even though they have similar versions of gcc and bison installed.
