I think it was caused by:
2004-11-01 Andrew MacLeod <[EMAIL PROTECTED]>
PR tree-optimization/16447
* tree-cfg.c (bsi_commit_one_edge_insert): Rename from
bsi_commit_edge_inserts_1, and make funtion external. Return new block.
(bsi_commit_edge_inserts): Use renamed bsi_commit_one_edge_insert.
* tree-optimize.c (pass_cleanup_cfg_post_optimizing): Enable listing.
* tree-flow.h (bsi_commit_one_edge_insert): Extern decl.
* tree-outof-ssa.c (rewrite_trees): Don't commit edges here.
(same_stmt_list_p): New. Return TRUE if edge is to be forwarded.
(identical_copies_p): New. Return true is two copies are the same.
(identical_stmt_lists_p): New. Return true if stmt lists are the same.
(analyze_edges_for_bb): New. Determine how best to insert edge stmts
for a basic block.
(perform_edge_inserts): New. Determine what to do with all stmts that
have been inserted on edges.
(remove_ssa_form): Analyze and commit edges from here.
Aka I cannot reproduce it with a tree right before but I can right after (well really
two patches after but
that other patch is a removal of unused code).
