This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase
Reported at https://github.com/gbiggs/hokuyoaist/issues/10
The simplest fix would be to make the stringstream mutable. That would have no ABI impact (although the extra 'const' on the what() member functions in C++11 would mode is an ABI break, and one that makes no sense whatsoever, because those functions should have been always const).
