            Bug ID: 98025
           Summary: [11 Regression][CET] libphobos: dub segfaults when
                    built with gdc 11
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org
          Reporter: ibuclaw at gdcproject dot org
  Target Milestone: ---

Following on from pr95680, the layout of the Fiber class changes when libph=
obos
is built with -fversion=3DCET.  This breaks user code that implement their =
own
fibers based off core.thread unless they also compile with -fversion=3DCET =
as
well.

So when libphobos is compiled with --enable-cet, this needs to be also reco=
rded
in gcc.config to persist in the ABI.  Not just as an internal implementation
detail.=
