Bug ID: 85104
Summary: double underline in a C++ error: duplicate const
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
The redundant const keyword in the error below is underlined twice in GCC 8.
GCC 7 underlines it just once so it seems like something is amiss.
$ cat u.C && gcc -S u.C
const int const i = 0;
u.C:1:11: error: duplicate ‘const’
const int const i = 0;
