[Help-glpk] Can you help me?

 Hi,

    My LP is below:

\* Problem: sample *\

Minimize
 obj: + x1

Subject To
 p: - x2 + x1 >= 1

Bounds
 -2147483648 <= x1 <= 2147483647
 -2147483648 <= x2 <= 2147483647

End

   I use GLPK to solve it, result is below:

z = -2.147483648E9; x1 = -2.147483648E9; x2 = -2.147483649E9

   "x2" is out of boundary, it seems some thing wrong, can you tell me why?

   Thank you very much!
