            Bug ID: 97538
           Summary: ICE in during GIMPLE pass: wrestrict
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
                CC: msebor at gcc dot gnu.org
  Target Milestone: ---
              Host: x86_64-linux
            Target: aarch64-linux-gnu

The following fails with a cross compiler:

$ cat restrict.C
void *b, *c;
struct H {
  virtual bool accept(const char *, unsigned long, int *, bool);
};
char accept_bt[1], accept_cd[1];
int accept_cb;
bool accept_cb_0;
class t : H {
  bool accept(const char *, unsigned long bd, int *bg, bool) {
    long bu = sizeof(int) + bd;
    char *bw = bu > sizeof(accept_bt) ? new char : accept_bt,
         *cf = bd ? new char : accept_cd;
    __builtin___memcpy_chk(b, c, bd, 0);
    if (bw != accept_bt)
      delete bw;
    bool ci = cj((int *)cf, bg), atran = bp && accept_cb_0;
    atran &&ci &&cm(&accept_cb);
  }
  bool cj(int *, int *);
  bool cm(int *);
  bool bp;
};
void bj() { new t; }

Created attachment 49434
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49434&action=edit
proposed patch in testing

Ranger was returning undefined, which caused get_size_range() to use an
uninitialized wide_int.

I am testing the attached patch.

These bug reports have been incredibly useful.  Thanks for reporting them.

commit r11-4336-g16e2427f50c208dfe07d07f18009969502c25dc8

    Handle undefined ranges in get_size_range.

    An undefined range was leaking through to the end of this function,
    which leads us to use an uninitialized wide_int.

    gcc/ChangeLog:

            PR tree-optimization/97538
            * calls.c (get_size_range): Handle undefined ranges.

    gcc/testsuite/ChangeLog:

            * g++.dg/pr97538.C: New test.
