Some ugly output..

The relevant part is this one, I guess:

Yes, of course. There doesn't seem to be a maintainer to CC. I can look into it later.

[peti]

There is probably not much the average Nixpkgs maintainer can do about a bug in GCC. You should really report this to gcc.gnu.org.

[edwtjo]

I didn't mean fix the bug :) Just going through the nixos patches for the package and the gcc bug database in search of similar bugs, in case there is a patch. Otherwise of course I'll file a bug.

[edwtjo]

Couldn't find any appropriate related bug. As expected, the segault also occurs without using any patches. Filed under 60015

[edwtjo]

I'll look into upgrading the package as a workaround.

[vcunat]

Could it be a problem that you have gcc-4.8.* in stdenv and use gcc-4.6.* parts?

[vcunat]

It builds now 14a6a059f according to @7c6f434c, so we close this?

[edwtjo]

Thanks @7c6f434c! I didn't realise you could substitute the stdenv gcc like that.
