patch.diff to reproduce
I haven't been able to get a small reproducer, the error seems to happen
sometimes dependent on random line changes. Easiest way is (all open source):
1) git clone <a href="mailto:git@github.com">git@github.com</a>:DynamoRIO/dynamorio.git (or use https:// as in
<a href="https://github.com/DynamoRIO/dynamorio">https://github.com/DynamoRIO/dynamorio</a>)
2) Go to revision git checkout 425413dbf134a46ae7a43d59b683ab350d72a85b
3) git apply patch.diff
4) git diff | ./clang-format-diff.py -p1

The problem is the random white space in "after formatting" that sometimes
seems to happen dependent on random line changes. I have not been able to find
a deterministic way, in particular a smaller example to reproduce other than
this one.</pre>
