            Bug ID: 94273
           Summary: ice in splice_child_die, at dwarf2out.c:5657
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

Created attachment 48085
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=3D48085&action=3Dedit
gzipped C++ source code

For the attached C++ source code, with recent gcc trunk, does this:

../tdutils/td/utils/logging.cpp:263:1: internal compiler error: in
splice_child_die, at dwarf2out.c:5657
  263 | }  // namespace td
      | ^
0x7064f4 splice_child_die
    ../../trunk.git/gcc/dwarf2out.c:5657
0x7064f4 gen_member_die
    ../../trunk.git/gcc/dwarf2out.c:25154
0x7064f4 gen_struct_or_union_type_die
    ../../trunk.git/gcc/dwarf2out.c:25265
0x7064f4 gen_tagged_type_die
    ../../trunk.git/gcc/dwarf2out.c:25466

Compile line needs flag -g1.

I'll have my usual go at reducing the code and finding a set of dates
where it first starts to go wrong.=
