I agree with you. This buf refers to mingw, I think, it could be closed.
Unfortunately, real application slows down to 30 times! But it's very hard to
"extract" bug from there because it is rather complicated and multi-threaded.
Also I have no profilers for Windows except gprof which is useless here.
Compiled on Fedora (GCC 4.6.3) application works fine.
I assume that the problem is with libgfortran, because if I run old application
(compiled with GCC 4.4.0), but with new gfortran.dll in PATH it works exactly
as bad, as new one.
