Summary0000376: unsigned long long constant becomes signed
DescriptionI have newest why and jessie and simple sample .c file: /*@ ensures \result == 1; @ */ int always_one(unsigned long long a) { if (a <= 0xFFFFFFFFFFFFFFFFull) return 1; return 0; } I run following command line: $ frama-c -jessie -jessie-atp simplify ull_constant.c which produces incorrect lemmas because this big constant becomes -1

 Fixed in Frama-C kernel (cil/src/cil.ml, function parseInt): integer constants (constructor CInt64) now keep their original string representation
