ocaml-zarith-devel.s390x: W: executable-stack /usr/lib64/ocaml/stublibs/dllzarith_c_stubs.so The binary declares the stack as executable. Executable stack is usually an error as it is only needed if the code contains GCC trampolines or similar constructs which uses code on the stack. One common source for needlessly executable stack cases are object files built from assembler files which don't define a proper .note.GNU-stack section. ocaml-zarith-devel.s390x: W: invalid-license-exception OCaml-LGPL-linking-exception ocaml-zarith.s390x: W: invalid-license-exception OCaml-LGPL-linking-exception ocaml-zarith.src: W: invalid-license-exception OCaml-LGPL-linking-exception The ' WITH ' license exception of the License tag was not recognized.

Binaries linking against this static library can't be properly debugged. ocaml-zarith.s390x: W: unstripped-binary-or-object /usr/lib64/ocaml/zarith/zarith.cmxs stripping debug info from binaries happens automatically according to global project settings. So there's normally no need to manually strip binaries. Left over unstripped binaries could therefore indicate a bug in the automatic stripping process. 3 packages and 0 specfiles checked; 0 errors, 6 warnings.
