[Bug middle-end/78370] Missing uninitialzed warning


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78370

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
In this case, GCC does not know that a escapes only at func2 so it assumes
func1 touches a.  I think there is a bug which says the same thing already but
I am too lazy to look for it right now.  PR 24639 might link to it.
