                    0x80000000
           Product: gcc
           Version: 3.4

Compile a program like this
gcc test.c main.c -fprofile-arcs -fvpt -O3
and run the resulting program and you will recieve an error:
profiling:/home/gates/pinskia/src/testl/test.gcda:Overflow merging
::::::::::::::
test.c
::::::::::::::
int mod(int i, int j)
{
        return i % j;
}
::::::::::::::
main.c
::::::::::::::
int mod(int,int);
int t;
int main()
{
        int j = 0x80000000;
        t = mod(0, j);
}
