Re: GCC 2.95.2 bug with float parameters

[Joe Weening <jweening at ccrwest dot org>]

A few days ago I sent the following bug report.  I forgot to mention
that the program was compiled with "-mcpu=ultrasparc".  (This was the
default on the system where I originally discovered the bug.)  With
this option, it fails on gcc 2.95.1 as well as 2.95.2.
