### Description :
Program o.i is defined for a x86_64 architecture according to:
$ ~/ppc/bin/toplevel.opt -val -obviously-terminates o.i -machdep x86_64 -no-val-show-progress -unspecified-access -val-signed-overflow-alarms -no-collapse-call-cast
Compiling and executing o.i:
$ gcc o.i show_each.c -o o
t3.c: In function ‘func_31’:
t3.c:281: warning: large integer implicitly truncated to unsigned type
t3.c:299: warning: comparison of distinct pointer types lacks a cast
$ ./o
...
[value] Called Frama_C_show_each({3203885237})
However, parsing and printing o.i into t.i yields a program that computes differently when compiled:
$ ~/ppc/bin/toplevel.opt -machdep x86_64 o.i -print > t.i
$ gcc t.i show_each.c -o t
$ ./t
...
[value] Called Frama_C_show_each({4108310006})
