            Bug ID: 93466
           Summary: [9/10 regression] New naming scheme for
                    -fprofile-dir=<dir> dump files hits filename length
                    limits
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hubicka at gcc dot gnu.org
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

Filename length limit for ext4 is 256 characters which is not that hard to hit
with the new flattened names (which use # instead of directory structure)
