If you are watching a pointer cast to a char in the Debug window in
QuickC Version 2.00, the machine hangs. Other casts perform as
expected. The example below demonstrates the problem.

Microsoft has confirmed this to be a problem in QuickC Version 2.00.
We are researching this problem and will post new information as it
becomes available.

In the QuickC environment, compile with debug options on. Next, set a
Watch on a pointer and cast it to a char. For example, enter the
expression "(char) intptr" (without the quotation marks). When this
expression is entered, the mouse cursor disappears and QuickC no
longer accepts any keyboard input.

Code Example
------------

char near * chptr;
int near * intptr;
float near * floatptr;

void main (void)
{
  chptr = (char near *) 1;
  intptr = (int near *) 1;
  floatptr = (float near *) 1;
  chptr = (char near *) 2;     /* put breakpoint here */

}

QuickC Versions 1.x do not exhibit this problem.
