1/ Don´t mark games-related bugs as blocker... 

http://www.gentoo.org/proj/en/desktop/games/index.xml#doc_chap5_sect4

2/ Reopen after you have recompiled your entire system with sane C[XX]FLAGS and
the problem still occurs then.

-mfpmath=sse is known to be troublesome

i'd say try rebuilding wormux and its direct dependencies w/out that flag first
