            Bug ID: 110146
           Summary: ICE in
                    riscv_vector::function_builder::add_unique_function()
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: palmer at gcc dot gnu.org
  Target Milestone: ---

A few of us were talking about this in the patchwork sync today, I think Juzhe
might have a fix already.  I'm getting a few thousand ICEs running the test
suite, they started yesterday for me.

Hi Palmer,

It should be fixed already as I understand on June 06, give or take. Do you
still meet such issues from the upstream?
