[cfe-dev] ld taking too much memory to link clang

[Andre Cunha]

I also found it strange that ld wasn't being killed, and was instead
causing my computer to freeze. I made a "while (1) malloc(...)" test
program, and it gets killed when I run it. Very strange... I'll contact
someone from Fedora about this.

I'll also try to use gold instead of the traditional ld. Thank you for the
suggestion!
