C++ single step in debugger throws an exception
问题 I have a C++ app that will throw an exception when I try to single step from a breakpoint. For example: 1) Start app from VS2010 0 debugger is attached. 2) Set a breakpoint. It doesn't seem to matter where. 3) Do something in the app so that it hits the break point. ** VS2010 hits the break point 4) Single step the debugger to the next line of code. VS2010 pops up a message box with this exception: "Unhandled exception at 0x087df66f in SimpleGraphSDI.exe: 0xC0000005: Access violation." Note
