I get a similar problem under gcc-2.5.5 running under ISC Unix on a i486
PC.  Very likely this is because of the following, taken from PROBLEMS
in the gcc-2.5.5 FSF distribution:

    124. On the 386, bad code results from foo (bar ()) when bar
    returns a double, because the pseudo used fails to get preferenced
    into an fp reg because of the distinction between regs 8 and 9.

We'll probably have to wait till the FSF fixes this.

Good Luck:
