[backport:2.5] [!528] Work around a nasty compiler bug in GCC 6.3 (!530) · Merge requests · Core Modules / dune-common

Steffen Müthing requested to merge cherry-pick-9a9fceea-2 into releases/2.5 Jun 29, 2018

GCC 6.3 errors out with an ICE or simply hangs when instantiating a certain variant of operator^= on BitSetVectorReference. This patch works around the problem by forcing the actual XOR instruction into a separate function for that compiler. The workaround is probably horribly slow, but it shouldn't have any impact on unaffected compilers.

This probably needs backporting.
