Bug ID: 81099
Summary: A single `decltype(this)` at top level triggers 2
identical error messages
Product: gcc
Version: 7.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: iamsupermouse at mail dot ru
Target Milestone: ---
If `decltype(this)` is used at top level, it triggers *two* identical error
messages. For example:
using T = decltype(this);
Results in:
<source>:1:20: error: invalid use of 'this' at top level
using T = decltype(this);
^~~~
<source>:1:20: error: invalid use of 'this' at top level
On the other hand, following:
auto x = this;
// al well as `using T = decltype(*this);`
triggers a *single* error message:
<source>:1:10: error: invalid use of 'this' at top level
auto x = this;
^~~~
