Whoops, duh, dinkumware is ms. Never mind, it was a dumb joke anyway.

Fair enough! I still disagree, but I guess my task now is to get Dinkumware
and Roguewave to change their implementations, and come back. I don't suppose
you'd be swayed by Microsoft? I didn't think so ;-)

I'm not erring. We changes this behavior on purpose, after having also checked
that *2* other, completely independent, implementations agree (ie, Dinkumware
and Roguewave).

You're right! Sorry; I apparently jumped to a conclusion while testing (but I
did test!)
I still disagree that an 'e' with no digit following can be reasonably
construed as part of an improperly-formatted flo

You are of course wrong. Parsing something like "59e" as an integer type of
course succeeds and gives "59". Really, we have *tons* of testcases about that
in the testsuite. We know what we are doing ;)

Followup: This still fails even if you're trying to pipe it into an integer
and not a double. Integers, as per 22.2.3.1 in C++98, do not have an optional
'e' after them. (Though of course you could *cast* a
--- Comment #4 from lpsmith at u dot washington dot edu 2010-08-13 20:34

Yes, exactly! Which is why the 'e' should not be parsed at all unless there is
an optional sign and a compulsory digit following it. The 'e' in general is
not compulsory. '59' is a valid double.
The context

By the way, if you read 22.2.3.1 in C++98, it's clear that 'e' is *not* just
any other character: after 'e', a sign is optional but at least a digit is
compulsory.

Is the reasoning explained somewhere?

Yes, this is intended. We even have testcases about that.
