It depends on what you call "broken software".  Would GCC stop being "broken 
software" if we paper over this particular bug?  What about papering over the 
hundreds of other bugs we know GCC contains?  We would need some criterion.

This bug has been known for years and seems to occur extremely rarely in 
pratice, so why rushing to paper over it now?  Just because it's Sandra and 
we know that GCC guys are extremely gallant? :-)
