Greetings,

That version of gcc seems to be outdated now. For that major version its

on 7.4 now so you may want to try that to see if its already been fixed

as a regression. If not thats considered a serious regression and should

be reported. If Finkel can also send me a log of the build utput I can

probably tell him how to get a trace but its a little hard to tell without

that.

Regards,

Nick
