[Bug libstdc++/14563] new/delete much slower than malloc/free

Subject: Re:  new/delete much slower than malloc/free

Dear All,

I do apologise,  I missed the necessity to feedback and was supposing that
the necessary fixes would feed through to the next gcc release bundled in
with Cygwin.  As far as I was concerned, the problem was sufficiently
"fixed" by reverting to 3.2.  Obviously, I will take a look at the patches
and see how they can be applied to octave.  If any blinding flashes of
inspiration occur, I will report back to you asap.

One thing that I get no sense of from the thread is why the Mingw/Cygwin
gcc-3.3 is so very bad, even in comparison with what you guys were finding.
Perhaps, I should try the tests with -sjlj disabled first, since the
profiling at first mislead us (well, me, at least) into believing that the
problem lay entirely there?  Anyway, I will find a "victim" machine onto
which to install Cygwin and gcc-3.3 (I might as well make the problem as bad
as possible!).

Best regards and thanks for your efforts.

Paul Thomas
