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.

I should clarify .. Of course I understand what the error message means and why it happens. The mystery is that it only happens on a single machine, and not on other nearly identical machines. If someone else sees this, let me know ...

I've solved this now. See 2162d09b2c9e138779d95f1fc7c3409765a5a40c.
