This is bison 2.0.
The latest version is 2.3. If haven't found anything in the ChangeLog which
sounds like there was a bug fix in this area.

If I remember correctly this was a bug with bison itself. What version of
bison are you using? I suggest to simply use -fno-strict-aliasing for this
generated file.

Bingo -fno-strict-aliasing does the trick. But what shall I do ? This is a
generated Bison parser.

Does -fno-strict-aliasing? Does adding that option with -O3 does that fix the
issue?

-Wstrict-overflow=5 doesn't seem to be available in 4.1.2
-fwrapv didn't make a difference.

Could you try to compile it by adding -Wstrict-overflow=5 as the last warning
flag (after -Wall)?
Independently, could you try to compile it by adding the -fwrapv flag?
