--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
Reduced test-case:

$ cat ~/Programming/testcases/AtomicFile.cpp.i
namespace std {
typedef char string;
class runtime_error {
public:
  runtime_error(string);
};
} // namespace std
#pragma GCC push_options
namespace fmt {
namespace {
__attribute__((always_inline)) auto format() -> std::string {}
#pragma GCC pop_options
} // namespace
} // namespace fmt
namespace core {
class ErrorBase : std::runtime_error {
  runtime_error::runtime_error;
};
class Error : ErrorBase {
public:
  template <typename... T> Error(T &&...);
};
template <typename... T> Error::Error(T &&...) : ErrorBase(fmt::format()) {}
} // namespace core
void commit() { core::Error(); }

$ ./xg++ -B. ~/Programming/testcases/AtomicFile.cpp.i -c

Note it crashes if I enable inlined dumps:
