This is an issue already seen, expecially on amd64, see bug #135040 for more info (no fix actually....)
@Matteo: ok, so I just wait for bug #135040?
Created attachment 88940 [details, diff] change 'char *add' to 'int *add' I grep'ed the source and this seems just fine. (I am on x86-only so cannot test.)
Just realized that 'int add' instead of 'int *add' could be better. :)
Created attachment 88941 [details, diff] version 2 Ok, changing 'char *add' to 'int add' seems fine. Then memcpy complains. Changing 'add' to '(char *)add' compiles. Casting this way may not lose precision? :)
Please apply this patch
in CVS as *-r2.
