--- Comment #19 from Paul Smith <psmith at gnu dot org> --- Hi; is there a next step for this? I understand there's some concern that we should be asking GDB to improve their capabilities but in the meantime can we get GCC to emit the previous format? It would be great if this could be fixed for GCC 7.3. I found another issue in GDB finding types containing defaulted template arguments, but this problem exists in all versions of GCC so I filed the issue against GDB instead. No response so far. https://sourceware.org/bugzilla/show_bug.cgi?id=22013 I also posted a question to the GDB mailing list asking for some conversation around this issue, but also no response so far. https://sourceware.org/ml/gdb/2017-08/msg00069.html
