The compiler was experiencing an internal compiler error (ICE) when the is_accessible feature was used with anonymous unions. This commit fixes the issue by adding a check for the otype (the type being accessed) in the accessible_p function within search.cc. This ensures that the compiler correctly handles access checks for members of anonymous unions.
