Can not show the arrow marker when the excution stop at the breakpoint.

After building it, I launch the sample debug engine through Tool/Project Launcher.

A minute later,
The callstack window shows the stack frame information----It is correct.
And the breakpoint window shows the breakpoints which I have set.------It is correct too.

However, in the source code window, the arrow marker does not show.

Then, If I type the local variant in the immediate window and type enter, The program will encounter a exception,
The exception is "Unhandled exception at 0x3f25236e in devenv.exe: 0xC0000005: Access violation reading location 0x00000000"

The function which cause this exception is HeapSize in Visual Studio 9.0/VC/crt./src/msize.c, line:88.

Is there any hint to solve this bug?

BTW, The sample works well in my college PC.
