Hi Lucas, Jonas, twinkle has been marked for autoremoval from testing on 2016-08-27 due to this FTBFS. Building ucommon with GCC 6 instead of GCC 5 yields slight differences in the list of visible symbols.
How should this bug be dealt with? Is it not simply a matter of waiting for GCC 6 to become default, uploading ucommon with an updated symbols file and an ABI bump (if needed), and submitting binNMUs for dependent packages? If so, can this bug be downgraded to severity important until then? Regards, Peter
