Robert,
Recently you have expressed the opinion that sounds to me that GCC is
taking too much a cavalier approach to "undefined behaviour".
However, as long as you feed that line of thought with reasoning like
above, I don't see how the current trend will change. Or did you
express that opinion just as a matter of debate?
These things definitely have to be addressed on a case by
case basis. I know that Paul likes
to consider them all together, but I don't think that's helpful.
In the case of uninitialized variables, I really think that it is
appropriate in the default optimized mode to assume that
all variables are initialized.
In this case, it is easy to formulate a useful option to
initialized everything by default, so you can check/run
your code in that mode if you want.
