Quartus 12 crashes on gentoo

It turns out that tbbmalloc is the problem for the install too. After Quartus installs, the installer runs quartus to install the device support. That's when Quartus crashes.

What I did was watch the files as they were installed. when tbbmalloc* appeared in quartus/linux, I immediately moved them to the side.

With that kludge, I was able to get through the entire installation. There must be a more elegant solution but this way does work. If there was a single file that was the source of only tbbmalloc*, I could just remove it before starting the installer but I don't know what that file would be (if there even is such a file).
