I used VS2013 to debug the server, it shows:
Then I click Continue, it shows:
First-chance exception at 0x765722CB (KernelBase.dll) in server.exe: 0x40010005: Control-C.
If there is a handler for this exception, the program may be safely continued.
Please fix this bug!
Unhandled exception at 0x0046420D in server.exe: 0xC0000005: Access violation reading location 0x000000EC.
