Bug ID: 91112
Summary: Bad error message for virtual function of a template
class. Wrong "required from here" line number
Product: gcc
Version: 8.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ivan.kharpalev at gmail dot com
Target Milestone: ---

I expect to see number of the line that triggers instantiation.
gcc-7 and clang show it.
P.S.
It even does not show bad method invocation line if it was called via base
class pointer.

It only shows call line for the class itself
