            Bug ID: 89013
           Summary: ice for packed attribute
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

For this C source code on recent gcc trunk:

typedef struct {
} __attribute__((__packed__)) a;
typedef const a *b;
c(b *d) { b e = c(e); }

I get

This seems to go wrong sometime between revision 267300 and 267400.
