UTF8TOCP compiler warning with GCC 14.2

[boeckmann]

Is it the right places to report this? There is also something on sourceforge. Is the source on sourceforge the current one? Seems so judging by the last commit date.

cc utf8tocp.c -o utf8tocp -Wall -pedantic -Wextra -O3 -std=c89 -Wformat-security
utf8tocp.c: In Funktion »loadlookuptable.constprop«:
utf8tocp.c:158:28: Warnung: Arrayindex -125 ist außerhalb der Arraygrenzen von »short unsigned int[128]« [-Warray-bounds=]
  158 |     lookuptable[128 - 253] = 0x20AC;      /* add the euro sign */
      |     ~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~

No idea. Who knows. Important thing is it gets to the proper person. :)

Is the source on sourceforge the current one?

Yes, utf8tocp is hosted on sourceforge.

array subscript -125 is outside array bounds

Thanks! Fixed on trunk. Weird that earlier gcc weren't spotting this obvious issue.
