I think youwill be interested in egcs. It is an effort to make the gcc
development process more open to the public. Anyone can get egcs
snapshots so you can see if this problem has been fixed since the gcc
source code you are using. Here are some introductory pointers:
How to join: send mail to egcs-request at cygnus.com. That list is
under majordomo.
We have a web page that describes the various mailing lists and has
this information at: http://www.cygnus.com/egcs.
