>How-To-Repeat:
See above.

The cited line in the first error is the first local variable
declaration after the function header.  The last argument in the
function's parameter list is:

  void* data _U_)

which looks to me like some macro "_U_" should have either expanded to
nothing at all, or perhaps something else appropriate (although I
have no idea what it could be given the context).

(As a quick test, deleting the "_U_" did not change the behavior.)
