            Bug ID: 60503
           Summary: gcc looks for C++ attributes in the wrong place in a
                    lambda-expression
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: richard-gccbugzilla at metafoo dot co.uk

GCC accepts this ill-formed code:

  void f() { []() [[ ]] mutable noexcept {}; }

... and rejects this valid code:

  void f() { []() mutable noexcept [[ ]] {}; }

--- Comment #6 from Alvin Wong <alvinhochun at gmail dot com> ---
Still a problem with 12.2 / trunk using GNU attributes:


$ <<EOF g++ -x c++ - -c -fsyntax-only
auto a() {
    return [](int a) __attribute__((stdcall)) noexcept { return a + 1; };
}
EOF
<stdin>: In lambda function:
<stdin>:2:47: error: expected '{' before 'noexcept'
<stdin>: In function 'auto a()':
<stdin>:2:46: error: expected ';' before 'noexcept'
<stdin>:2:56: error: expected '(' before '{' token
<stdin>:2:56: error: expected primary-expression before '{' token
<stdin>:2:55: error: expected ')' before '{' token
