"reduced" testcase
I suppose it needs some minimal DECL_UID, this is as small as I can get it
(automated). Fails in verify_ssa compiling with -O2 -fno-tree-store-copy-prop
--param ggc-min-expand=0 --param ggc-min-heapsize=0.
tree-ssa-structalias.3.min.i:1098: error: definition in block 5 follows the use
for SSA_NAME: D.4370_29 in statement:
D.4369_26 = D.4370_29;
tree-ssa-structalias.3.min.i:1098: internal compiler error: verify_ssa failed
