Q47625: Trace Stops on Line Following a Loop Before Loop Is Done

In trace mode, CodeView stops on the line following a loop that does
not have open and close braces ({}), before the loop is done.

When tracing through a loop without the braces ({}), the trace stops
on the statement immediately following the loop each time through the
loop, giving the impression that the statement is being executed
inside the loop. Actual program execution is correct.

The following program was compiled with C Version 5.10 with the
command line

   cl /Zi /Od program.c

and run using CodeView 2.20, as follows:

    cv program.exe

The trace stops at the printf each time through the loop even though
printf is not part of the loop, but does not print anything until the
end of the program.

Sample Program
--------------

#include <stdio.h>

void main(void)
{
    int i;
    int count;

    count = 0;

    for(i=0;i<3;i++)
        if(i)
            count++;

    printf("Count is %d\n",count);
}
