Comment (by heisenbug):

 Replying to [comment:6 alexbiehl]:
 > Gabor, I am on OSX. Can you tell me where your code lives and what your
 build settings are? I will try to reproduce.

 I am in the context of branch `wip/T14626` in the central repository.
 There I build with basically unchanged `mk/build.mk` (i.e. `-O2`). I am
 pretty sure this patch from Simon '''alone''' works on all platforms. But
 I have no resources to validate it myself.
