/GX (Enable Exception Handling)
This option enables synchronous exception handling with the assumption that extern C functions never throw an exception. It is equivalent to /EHsc.
/GX is in effect, by default, when you compile from within the development environment. By default, /GX- is enabled when using command-line tools.
For more information, see C++ Exception Handling.
