            Bug ID: 103910
           Summary: openjdk17 causes ICE on -O3 -march=opteron
                    -fchecking-new: during GIMPLE pass: aprefetch: in
                    gimple_build_call, at gimple.c:267
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: slyfox at gcc dot gnu.org
  Target Milestone: ---
            Target: x86_64-pc-linux-gnu

ICE initially noticed by Alexander Weber in https://bugs.gentoo.org/822690.

Here is the reduced test, fails on both gcc-12 and gcc-11.2.0. Note: it needs a
gch header.

//$ cat archiveBuilder.cpp
#include "precompiled.hpp"
void *operator new(unsigned long, void *__p) { return __p; }
#define MEMORY_TYPES_DO(f) f(mtNone, )
enum MEMFLAGS {};
#define MEMORY_TYPE_SHORTNAME(type, human_readable) MEMFLAGS type;
MEMORY_TYPES_DO(MEMORY_TYPE_SHORTNAME) struct GrowableArrayView {
  GrowableArrayView(int *, int, int);
};
int *GrowableArrayWithAllocator_data;
struct GrowableArrayWithAllocator : GrowableArrayView {
  GrowableArrayWithAllocator(int initial_max)
      : GrowableArrayView(GrowableArrayWithAllocator_data, initial_max, 0) {
    for (int i = 0; i < initial_max; i++)
      new (&GrowableArrayWithAllocator_data[i]) int();
  }
};
struct GrowableArrayMetadata {
  GrowableArrayMetadata(MEMFLAGS);
};
struct GrowableArray : GrowableArrayWithAllocator {
  GrowableArrayMetadata _metadata;
  GrowableArray(int initial_max)
      : GrowableArrayWithAllocator(initial_max), _metadata(mtNone) {}
};
struct SourceObjList {
  SourceObjList();
};
SourceObjList::SourceObjList() { GrowableArray(128 * 1024); }
