Failing testcase
Richard,
I hate to break the news to you but there are even more cases. Attached
is a file that produces this warning:
----------------------------
dof_renumbering.ii:51892: warning: '<anonymous>' may be used uninitialized in
this function
dof_renumbering.ii:51892: note: '<anonymous>' was declared here
----------------------------
The warning comes from using the unnamed object 'dfs_visitor()', which is
of this type:
----------------------------
struct empty
{};
struct dfs_visitor {
dfs_visitor() { }
dfs_visitor(empty vis) : m_vis(vis) { }
empty m_vis;
};
-------------------
I wished I could come up with a smaller testcase, this one is fairly
lengthy, though everything of importance happens in the last 20 or so lines.
Best
Wolfgang
