为什么在启用浮点exception之后，我得到了多个陷阱错误

环境Windows 10与MSVC2015专业，与/ EHa编译

我在做什么：启用浮点exception，以便能够在发生某些不良事件时捕获exception，仅用于debugging

码：

namespace debug_details { void (*defaultStructuredExceptionFunc)(unsigned int, PEXCEPTION_POINTERS) = nullptr; void my_trans_func(unsigned int exceptionCode, PEXCEPTION_POINTERS pExpInfo) { switch (exceptionCode) { case EXCEPTION_FLT_DENORMAL_OPERAND: case EXCEPTION_FLT_DIVIDE_BY_ZERO: case EXCEPTION_FLT_INEXACT_RESULT: case EXCEPTION_FLT_INVALID_OPERATION: case EXCEPTION_FLT_OVERFLOW: case EXCEPTION_FLT_STACK_CHECK: case EXCEPTION_FLT_UNDERFLOW: { _clearfp(); std::stringstream ss; ss << "floating-point structured exception: 0x" << std::hex << exceptionCode; throw std::runtime_error(ss.str()); } default: if (defaultStructuredExceptionFunc != nullptr) { defaultStructuredExceptionFunc(exceptionCode, pExpInfo); } }; }; void EnableFloatingPointExceptions() { unsigned int fe_value = ~(/*_EM_INVALID | _EM_DENORMAL |*/ _EM_ZERODIVIDE | _EM_OVERFLOW | _EM_UNDERFLOW /* | _EM_INEXACT*/); unsigned int mask = _MCW_EM; unsigned int currentWord = 0; _clearfp(); errno_t result = _controlfp_s(&currentWord, fe_value, mask); // https://msdn.microsoft.com/en-us/library/c9676k6h.aspx DVASSERT(result == 0); debug_details::defaultStructuredExceptionFunc = _set_se_translator(&debug_details::my_trans_func); // https://msdn.microsoft.com/en-us/library/5z4bw5h5.aspx float32 div = 0.f; float32 f = 15.f / div; float32 f2 = 30.f * div; } } // end namespace debug_details 

我期望EXCEPTION_FLT_DIVIDE_BY_ZERO ，但是

请帮忙了解发生了什么事？ 提前致谢！
