Thanks for the report. This bug has been reported upstream but there
hasn't been any updates yet. Feel free to give the upstream bug a
nudge, but until they investigate it there's not much I can do on my end
(I have very limited free time to work on the package nowadays). My gut
feeling tells me that this is actually a bug in the demangler, but I may
be wrong.
Cheers,
