--- Comment #4 from David Malcolm <dmalcolm at gcc dot gnu.org> --- FWIW the location information is available in the frame above: Breakpoint 6, invalid_nonstatic_memfn_p (loc=205792, expr=<function_decl 0x7ffff1a16900 f>, complain=3) at ../../src/gcc/cp/typeck.c:1834 1834 expr); (gdb) list 1829 if (complain & tf_error) 1830 { 1831 if (DECL_P (expr)) 1832 { 1833 error_at (loc, "invalid use of non-static member function %qD", 1834 expr); 1835 inform (DECL_SOURCE_LOCATION (expr), "declared here"); 1836 } within EXPR_LOCATION (arg): (gdb) up #7 0x00000000007b1a65 in resolve_args (args=0x7ffff1a14460 = {...}, complain=3) at ../../src/gcc/cp/call.c:4012 4012 else if (invalid_nonstatic_memfn_p (input_location, arg, complain)) (gdb) call inform (arg->exp.locus, "") /tmp/pr77777.cc: In function ‘int main()’: /tmp/pr77777.cc:11:9: note: x.f ~~^ so this location could be passed to invalid_nonstatic_memfn_p and a fix-it hint added.
