--- Comment #8 from Hans-Peter Nilsson <hp at gcc dot gnu.org> --- Supposedly viable workarounds: omit "-fno-omit-frame-pointer" or use "-O2". (required and necessary options for observation; omitting any of the "-f"-options compiles succcessfully: "-Os -march=v10 -fno-strict-aliasing -fno-delete-null-pointer-checks -fno-omit-frame-pointer -fno-inline-functions-called-once")
