    • re PR fortran/83344 (Use of uninitialized memory with ASSOCIATE and strings) · 5c60dbc1 
      2018-02-19  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/83344
	PR fortran/83975
	* resolve.c (resolve_assoc_var): Rearrange the logic for the
	determination of the character length of associate names. If
	the associate name is missing a length expression or the length
	expression is not a constant and the target is not a variable,
	make the associate name allocatable and deferred length.
	* trans-decl.c (gfc_get_symbol_decl): Null the character length
	backend_decl for deferred length associate names that are not
	variables. Set 'length' to gfc_index_zero_node for character
	associate names, whose character length is a PARM_DECL.

	PR fortran/83975
	* gfortran.dg/associate_22.f90: Enable commented out test.
