I have isolated the problem to gfc_itoa. gfc_itoa returns a string. The number
of digits is determined from the strlen of that string. At -m32, that string
length (digits, see below) is off by one. I instrumented write_decimal in
write.c to see this. I now will dig into gfc_itoa.
$ gfc -m64 pr38504.f90
$ ./a.out
sign=1
w=22, m=-1, digits=19, nsign=1
-9223372036854775808
$ gfc -m32 pr38504.f90
$ ./a.out
sign=1
w=22, m=-1, digits=20, nsign=1
