With the current master and releases/2.4 branch of dune-common the optimized compilation of bitsetvectortest does not terminate. In fact I terminated it manually after 2 minutes when gcc consumed 10gb of memory. The error seems to be cmake-related, because is depends on how optimization flags are passed:
If they are just passed via
CMAKE_CXX_FLAGS everything works nicely. (test2.opts)
If they are passed by
CMAKE_CXX_FLAGS_RELEASE and the buildtype release is selected the described error occurs. (test1.opts)
Both cases can be reproduced by the attached dunecontrol option files.
Update: The issue is not related to build types. It is triggered by passing both,
-O3, to gcc-4.9.2 on a 64bit Ubuntu 15.04.
