There is the Salford FTN95 personal edition which is both a superb
debugging compiler and offers optimization. It runs on Win32. Personal
edition means free for noncommercial use if I understand the license.

The Intel Fortran 95 for Linux is free and offers heavy optimization.
It's Win32 companion is not free.

Since both of these have had updates to cure bugs I expect that is
why you call them unstable. The g95 and gfortran GNU Compiler twins
are not really at a releasable stage so can not yet really be judged.
