Christophe Lyon <clyon at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |clyon at gcc dot gnu.org --- Comment #6 from Christophe Lyon <clyon at gcc dot gnu.org> --- Also seen on arm* targets: /gcc/testsuite/g++.dg/template/overload15.C:14:10: error: call of overloaded 'f<0>(char (*)[1])' is ambiguous /gcc/testsuite/g++.dg/template/overload15.C:15:10: error: no matching function for call to 'f<0>(char (*)[7])' Unlike you, I do see the new test pass on aarch64, except if I also use -mabi=ilp32. Is your aarch64-suse-linux-gnu configured with ilp32 by default?
