--- Comment #15 from David Binderman <dcb314 at hotmail dot com> --- >This is a 8 only regression. It has nothing to do with 7.2. Curiouser and curiouser. Richard Biener has just posted that 7.2-rc1 has been created from revision 250819. The small chunk of code I posted AFAIK goes wrong with revisions 250718, 250725, 250757, 250813, 250841. I am no expert in svn, but if 250813 and 250841 demonstrate the fault, then AFAIK something derived from 250819 should also show the fault. Unless you know different.
