            Bug ID: 23653
           Summary: ld SIGSEGVs when attempts to link sparc object with
                    x86_64 library (--enable-targets=all): assertion fail
                    ../../binutils-gdb/bfd/elfxx-sparc.c:1218
           Product: binutils
           Version: 2.32 (HEAD)
            Status: UNCONFIRMED
          Severity: normal

binutils-multitarget-sparc.tar.gz

Original failure was discovered when cross-compiling lua: build system
accidentally linked sparc objects into x86_64 libc:

    $ ${HOME}/dev/git/binutils-gdb-native-all-targets/ld/ld-new --eh-frame-hdr
-m elf_x86_64 -shared -o bug.so.5 bug.o ./libc.so.6 ./crtendS.o
    /home/slyfox/dev/git/binutils-gdb-native-all-targets/ld/ld-new: BFD (GNU
Binutils) 2.31.51.20180913 assertion fail
../../binutils-gdb/bfd/elfxx-sparc.c:1218
    Segmentation fault (core dumped)

Built binutils from master as:
$ ../binutils-gdb/configure --enable-targets=all --disable-werror

Object files are attached. Note: only bug.o is a sparc object.

$ file bug.o ./libc.so.6 ./crtendS.o
