FYI, I also encountered a gcc-4.3 miscompilation yesterday (an assertion

package seems to fix it.
I'm thankful that Cygwin exists and is the great product it is!
Because our gcc maintainer went missing. We hope Dave is ok, as we have
had no word from him. However, in the meantime, we've had another
person (Yaakov) volunteer to pick up the slack; the recent release of an
updated GMP package were requested by the new volunteer to facilitate
the upcoming release of gcc-$newer.
BUT, I just have an issue with GCC 4.3. I compiled some terse
numerical (~1500 lines worth) and got one set of answers (using g++)
and I got another set of answers using MinGW with 4.5. The MinGW
results were what I expect - the same as I got using SuSE 11.4 with
g++ 4.6. Also, the values I get using VC++ 2010.
Haven't had time to wade through the ~1500 lines of Runge-Kutta code
to find the needle-in-the-haystack.
