<pre>In:
<a href="https://github.com/froydnj/aarch64-xdata-bug">https://github.com/froydnj/aarch64-xdata-bug</a>
is an aarch64 windows .obj file, generated by "clang 8.0.0 tags/RELEASE_800/rc2
353414". Running `llvm-readelf -unwind $OBJ` produces an error message:
LLVM ERROR: .xdata must be at least 8 bytes in size
with truncated output.
I'm not sure whether clang is at fault here or whether llvm-readelf is doing
the wrong thing.
The preprocessed source for the file is included, and cmdline.txt contains the
command-line used to compile the file.</pre>
