使用VC2010（16.00.30319.01 for x64）编译QT4.8.4，编译时一切正常，但Release版的QtGui4.dll运行时错误，Debug版正常，谁知道为什么？
使用windbg加载QT自带例子：D:\qt\qt-sdk\demos\books\debug\books.exe
(9f0.790): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.
*** ERROR: Symbol file could not be found. Defaulted to export symbols for D:\qt\qt-sdk\bin\QtGui4.dll -

左看右看也没发现此函数有什么问题，按理来说vc的编译器应该不会有什么问题。
