             Bug #: 50228
           Summary: Incorrect line execution count.
    Classification: Unclassified
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gcc.hall@gmail.com


Source line 6625 is reported as having been executed more times than is
possible.

Secondly I saw that all the source lines in the function were executed at least
once, but it says "blocks executed 92%"

gcov 4.6.1, gcc 4.6.1 (-O0 -ggdb3 --coverage)

function Evaluate called 29903918 returned 100% blocks executed 92%
