--- Comment #10 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
So, after the change from fat to slim lto, I've added the CP2K SVN repo to use
gcc-ar (so that the instructions in comment #1 should still work).
Now, the issue discussed here fails to reproduce because during the lto phase
we run into:
/data/vjoost/clean/cp2k/cp2k/makefiles/../src/thermostat_methods.F:102:0:
