The compiler was crashing when the [[trivial_abi]] attribute was used in C++ template code. This commit fixes the issue by ensuring that the trivial_abi related logic is only applied when not processing a template declaration. This prevents the compiler from trying to perform cleanup operations at template parsing time, which is not necessary.
