Most MVPs agreed that, despite not being illegal in C++, throwing primitive types like int, long, etc., or similarly Windows-based ones like HRESULT, etc. is a coding horror as inabilities to catch those in the proper place will make the application crash with a hard post-investigation to determine where they are being originated.
I strongly recommend AGAINST using the /EHa compiler option. Either /EHs or /EHsc should ALWAYS be used, with /EHsc being preferable (it's faster because it assumes that extern "C" functions won't emit exceptions - while technically permitted by the Standard, sane code should never attempt to do such a thing, so giving up that ability is worth the performance gain).
And I am sure the comments will continue to grow and the conversation continue. This is how we all get better, by discussing and sharing and occasionally defending our practices. It's a must-read.
