I'm taking about VC++ 8.0's default alignment, of course.
Can you, using the code above, get â?? Implicit_Size_of_Int32 == -16 â??,
Mr. Seligman ?
Yes, as soon as you turn on runtime checks (/RTC), and of course
things change further with other optimizations.
Your code produces 8 in a debug build with all optimizations and such
off, but that's very nearly useless information.
