But it is strange that in a sequence InsertBranch - RemoveBranch - InsertBranch - RemoveBranch all operating on an identical instruction, the first removal is successful, while the second asserts ... following the commit of r161643 Can you shed some light on this, on where to look further for example? Thanks a lot, Bjorn
