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
