            Bug ID: 125066
           Summary: [17 Regression] ICE on qtwebengine-6.11.0
                    (clang::trivial_abi)
           Product: gcc
           Version: 17.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: slyfox at gcc dot gnu.org
  Target Milestone: ---

After #125022 being fixed I tried again to build qtwebengine-6.11.0. gcc-master
still fails. `cvise` extracted the following:

$ cat logging.cc.cc
class RepeatingCallback;
struct ScopedLogAssertHandler {
  ScopedLogAssertHandler(RepeatingCallback);
};
struct [[clang::trivial_abi]] BindStateHolder {
  ~BindStateHolder();
};
struct [[clang::trivial_abi]] RepeatingCallback {
  BindStateHolder holder_;
};
ScopedLogAssertHandler::ScopedLogAssertHandler(RepeatingCallback) {}
