re PR c++/79372 (ICE on C++ code with illegal decomposition declaration on x86_64-linux-gnu: in tsubst_decomp_names, at cp/pt.c:15599)
PR c++/79372
* decl.c (cp_finish_decomp): On error set decl type to error_mark_node.
* pt.c (tsubst_expr): Don't call tsubst_decomp_names on decompositions
with error_mark_node type.
* g++.dg/cpp1z/decomp25.C: New test.
