When running the following on trunk (d51e06c73c33b6c35ee47542a9674da63c6b7f07)
test.sh
```sh
clang++-18 -cc1 -std=c++17 -emit-pch -o qtooltip.cpp.oclango qtooltip.cpp
clang-18 -cc1 -x c++ -ast-merge qtooltip.cpp.oclango /dev/null -ast-dump-all=json
```
qtooltip.cpp
```cpp
template <typename> struct _Optional_payload_base {
template <typename, bool = false> union _Storage;
template <typename _Up> union _Storage<_Up> {};
_Storage<int> _M_payload;
};
_Optional_payload_base<int> _M_payload;
```
The second command crashes with this backtrace
```console
virtual clang::SourceRange clang::ClassTemplateSpecializationDecl::getSourceRange() const: Assertion `inst_from != nullptr' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
