warning: ‘void operator delete [](void*)’ called on unallocated object ‘juce::emptyString’ [-Wfree-nonheap-object]

Whilst compiling the current code in master in gentoo the QA checks in the package manager threw this warning:

QA Notice: Package triggers severe warnings which indicate that it
           may exhibit random runtime failures.
/var/tmp/portage/media-plugins/adlplug-9999/work/adlplug-9999/thirdparty/JUCE/modules/juce_core/text/juce_String.cpp:164:52: warning: ‘void operator delete [](void*)’ called on unallocated object ‘juce::emptyString’ [-Wfree-nonheap-object]
Please do not file a Gentoo bug and instead report the above QA
issues directly to the upstream developers of this software.

Some context from the compile log:

Seems like some crappy code in JUCE?
