Bug #: 57148 Summary: integer*4 fails to read largest negative number Classification: Unclassified Product: gcc Version: 4.6.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: ja...@hvdc.ca I am using MINGW32 build of GCC 4.6.2 on Windows 7 x64. Range of integer*4 is from -2147483648 to +2147483647. If you try to assign -2147483648 to an integer*4 variable, it gives an error saying too big for its kind.
