Well, to be fair enough, the number of miscompilations is not very large in
gcc. I think I have found 1 or 2 in the last 7 years or so, but at the same
time have filed >100 bugs in total. At least on major platforms, the number
of miscompilations is almost negligible, I'd say.

I have a couple of reports against icc, but I don't even know where I should
send them -- unless you pay, they don't even give you an email address for
bug reports. No wonder they don't fix the bugs they don't know about :-)
