            Bug ID: 124608
           Summary: [13 Regression] gdc bootstrap failure on
                    aarch64-linux-gnu
           Product: gcc
           Version: 13.4.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org
          Reporter: doko at gcc dot gnu.org
  Target Milestone: ---

with the gcc-13 branch 20260323, gdc fails to build on aarch64-linux-gnu. The
last successful build I have is 20260317.

gdc: internal compiler error: Segmentation fault signal terminated program d21

make[7]: *** Waiting for unfinished jobs....

I am using GCC 13 for the bootstrap, so it also could be an issue with the
20260317 compiler.
