VSCode logs
One of our developers have been seeing the following clangd crash when using
VSCode:
clangd:
/b/s/w/ir/kitchen-workdir/llvm-project/clang-tools-extra/clangd/Selection.cpp:201:
bool clang::clangd::(anonymous namespace)::SelectionVisitor::nodesCoverRange(
llvm::ArrayRef<const Node *>, unsigned int, unsigned int): Assertion
`R.isTokenRange()' failed.
The crash can be reproduced using the files in
<a href="https://fuchsia-review.googlesource.com/c/fuchsia/+/258851">https://fuchsia-review.googlesource.com/c/fuchsia/+/258851</a>. For the crash to
happen, it's necessary need to have two editors open side-by-side on these
exact files: page_storage_impl.cc, live_commit_tracker.cc
The logs from VSCode are attached as well.</pre>
