我用向导建了一个最简单的objectarx程序，编译通过。可是在调试的时候系统给我提示
Windows has triggered a breakpoint in acad.exe.
This may be due to a corruption of the heap, which indicates a bug in acad.exe or any of the DLLs it has loaded.
This may also be due to the user pressing F12 while acad.exe has focus.
The output window may have more diagnostic information.
