[plt-scheme] drscheme in Xorg-7.0?

I have seen this problem with several versions of gcc, its drscheme-301 compiled
from the source tarball.

This issue has seemingly been around for awhile, the backtrace I get from it is
the same one as is posted on ticket 6717:

If you need any other info, let me know (I am the maintainer of the Gentoo
ebuild for this, if there is a patch I will gladly put it in the ebuild)
