zf <zfefm at gmx dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |zfefm at gmx dot de --- Comment #2 from zf <zfefm at gmx dot de> --- I have the same problem when I try to build gcc (4.92 or 5.1) on my Macbook OS 10.9.5. On my MacPro, also runing 10.9.5, this builds without problems. I have not yet found the reason for this difference.
