seems to work at least on my 64bit maschine tested against 5.1.6 and
latest snapshot. Maybe someone can verify for 32bit maschines.

Does this patch fix it for you?

(gdb) p word[w_idx]
$1 = -61 'Ã'

in my native mind this should not result in a negative number. This
seems to be related to wider datatypes on 64 bit maschines possible a
compiler flag issue ...

ah got it i had to run php -e 
(gdb) p word[w_idx]
$1 = -61 'Ã'
(gdb) p toupper(word[w_idx])
$2 = 28518
(gdb) p isalpha(toupper(word[w_idx]))

Program received signal SIGSEGV, Segmentation fault.
0x0000000200e4eced in isalpha () from /usr/lib/libc.so.12
