A depenent type is possible in C-only path, add a proper handling when
checking the enum constant.
Fixes https://github.com/llvm/llvm-project/issues/62446
Differential Revision: https://reviews.llvm.org/D150948
when it had been instantiated from a partial template specialization with different
template arguments on the containing class. This fixes:
(`#60778 <https://github.com/llvm/llvm-project/issues/60778>`_).
+- Fix a crash when an enum constant has a dependent-type recovery expression for
+ C.
