do-while loops are converted to this form by the compiler (as of version 4, use the -fdump-tree-* to see the IL), so the problems you are observing must be caused by something different. > use C control constructs rather than gotos. With GCC version 4, this will have no effect because the gimplifier converts everything to goto-style anyway. _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
