Did you report this upstream?
Comment by Harri (episyron) - Saturday, 31 May 2014, 16:42 GMT
Nope. I skimmed luxrender bug reports, but didn't find anything related.

Well what can we do to work towards this except for posting stuff on the luxrender bug tracker?

It seems that it is just another bug in GCC. I will rebuild the package with clang.
