           Summary: Entering incorrect information to scanf breaks scanf.
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gaffneyc@student.gvsu.edu
                CC: gcc-bugs@gcc.gnu.org

When using scanf and you enter an incorrect value ie (scanf("%lf", &var) and 
you enter a scanf breaks and each succesive call will simply be passed by.

Some example code:
doube *myVar;
while(!scanf("%d", myVar)) {

Should reask the user for scanf but instead it will continue looping. The 
problem is that stdin is not being set to EOF. I tried under the default cygwin 
gcc version and gcc 3.2.2 under gentoo linux. Bother give the same result. When 
compiled under mingw and visual c compiler it works as expected.
