["wanderer at rsu dot ru" <gcc-bugzilla at gcc dot gnu dot org>]

I have problem with bootstrap current mainline CVS.
Bootstrap terminated with error log:

I think this problem doesn't related gcc version used for bootstrap,
but I test and reproduce problem with FreeBSD system compiler gcc version 
3.2.2 [FreeBSD] 20030205 (release) and gcc version 3.4.3 20040909 (prerelease).
