Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |FIXED Target Milestone|--- |8.0 --- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to rene.rahn from comment #0) > g++ (Macports gcc8 8-20170604_1+universal) 8.0.0 20170604 // on mac: Darwin > Kernel Version 16.7.0 This was already fixed for gcc-8 by r251433 last August (you're using a snapshot of GCC 8 from nearly a year ago, which will be very buggy compared to more recent snapshots). The fix is too complicated to backport, so the bug is still present in the GCC 7.x and 6.x release series.
