Bug ID: 87750 Summary: Failed compilation / parsing of template member call after 'using' declaration Product: gcc Version: 8.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: mark.atkinson99 at gmail dot com Target Milestone: --- Problem code: https://godbolt.org/z/3IpLz1 This is a cut down sample of real code that no longer compiles in gcc 8.x. On godbolt the sample does not compile under 8.1, 8.2 & current trunk, but works in previous gcc. The first call marked (1) compiles in gcc <= 7.x, clang, msvc & icc. The call marked (2) is accepted by gcc 5.x to 7.x and clang 7 but not clang 5 & 6. I can work around it, but can you advise root cause.
