#100 return local variable

[Yevgen Ryazanov]

In tixHList.c, NewElement(), line 2788, local variable buff is assigned to a variable of outer scope, name, which is used later in this function out of the scope of variable buff.
It was found by Coverity checker RETURN_LOCAL, and it is still true in last release, 8.1.5.a2.

[Jeffrey Hobbs]

moved to func scope.
