------- Comment #2 from hp at gcc dot gnu dot org 2007-12-08 00:44 ------- I'm not sure this is related but a while ago I ran valgrind hoping to spot the cause for another bug, and valgrind complained about tree-ssa-alias-warnings.c:processed_func_p (tree func) which hashes the address of its argument: *slot = &func; where it probably meant *slot = func; This bug looked like it could mask warnings or possibly cause multiple warnings for the same code. Another solution would replace the machinery where this is used with a pointer_set for the hashing, or available bits in the tree to mark the visitedness.
