------- Comment #2 from burnus at gcc dot gnu dot org 2007-04-13 15:08 ------- Well, gfortran is right: x'80000000' = 2147483648 > 2147483647 = huge(msk1) and o'37700000000' = 4278190080 > 2147483647 = huge(msk4)
Thus the BOZ numbers are too big for the 4-byte variables. The other compilers simply allow the variable to overflow, which gfortran does if one uses the option -fno-range-check. With that option the variables get initialized to: msk1 = -2147483648 msk4 = -16777216 Therefore, - If you don't want the overflows, check your program and use, e.g., 8-byte variables - If the overflows are on purpose, use the option -fno-range-check PS: I have a patch awaiting review which mentions the -fno-range-check option in the error message. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31563
