            Bug ID: 31377
           Summary: [libabigail] abidiff does not handle some flex array
                    conversion
           Product: libabigail
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: default
          Assignee: dodji at redhat dot com
          Reporter: david.marchand at redhat dot com
                CC: libabigail at sourceware dot org
  Target Milestone: ---

Following a tentative change submitted by a DPDK contributor, like

-       __extension__ uint8_t action_data[0];
+       uint8_t action_data[];

our ABI check raised a libabigail exception:

  type size hasn't changed
  1 data member change:
    'uint8_t action_data[]' has *some* difference - please report as a bug

So I am following the suggestion, and reporting a bug :-).
Binaries and commandline can be found in the archive attached to this bz.
