Fwd: [Bug c++/14563] octave built under Cygwin very slow]

[Paul Billings]

I have read as much as this thread as I can, including all the traffic on
the gcc bugzilla report.  I gather that there are two issues, possibly
related: 1) SJLJ exceptions and 2) allocations w/ new are very slow.  My
question is do these issues still exist in the cygwin-distribution of gcc
3.4.4 (where SJLJ is enabled)?  Is the problem present in the currently
distributed octave executable in cygwin?
