Comment (by tczorro):

 Replying to [comment:2 dstrubbe]:
 > Hi, please be more specific, so we can try to figure if there really is
 a bug here. What code? What kind of problem arose? What variants for libxc
 are you using? Did you run its testsuite?

 Some code in LibXC gives notably different results with -O3. -O1 is safe.
 The failing test is related to kernels, i.e. second order derivatives of
 the functionals, which are not used as frequently.
