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
