Q59315: CodeView Trace Skips Statement Following Switch Statement

CodeView incorrectly maps assembly level instructions to source code
in the first statement following a switch statement with seven or more
cases.

As shown in the code sample below, the statement following the switch
is executed correctly, but CodeView steps over the statement while
tracing in source mode. In mixed source and assembly mode, the
statement following the switch may be traced into.

Sample Code
-----------

# include<stdio.h>

void main(void)
{

   short tag, marker;

   marker = 0;
   tag = 5;

   switch(tag){
      case 1:
         break;
      case 2:
         break;
      case 3:
         break;
      case 4:
         break;
      case 5:
         break;
      case 6:
         break;
      case 7:
         break;
      default:
         break;
   }

      marker = 2;

}
