Zip archive with libbug.o object file to reproduce the error
Running ranlib (Xcode 9) on a library generated by llvm-ar results in a
malformed archive.
Using the attached object file libbug.o, there is no error using the system
tools:
- rm -f libbug.ar.a
- ar rcs libbug.ar.a libbug.o
- ranlib libbug.ar.a
- nm -g libbug.ar.a (no error)
Now with llvm-ar, we get an error:
- rm -f libbug.llvmar.a
- llvm-ar rcs libbug.llvmar.a libbug.o
- ranlib libbug.llvmar.a (system ranlib, with llvm-ranlib no error happens)
- nm -g libbug.llvmar.a (errors) (also errors with llvm-nm)
The error is:
"nm: libbug.llvmar.a truncated or malformed archive (terminator characters in
archive member ".o" not the correct "`\n" values for the archive member header
at offset 864)"
(bug was discovered in LDC when using the internal archiver (LLVM). See
