Please attach the entire build log to this bug report.
Created attachment 300723 [details] build.log here it is. my default boost version is 1.46.
You probably updated your boost library but you forgot to rebuild its reverse dependencies. rebuild rb_libtorrent and try again. reopen if needed
that helped, thanks (most probably gcc update issue).
