Whereas I'm all for providing alternate memory management policies (we are very close to that in the v7-branch and I promise further progress during the next months) I fail to properly appreciate the actual details of this issue: which applications are actually penalized, which are the alternatives, something more concrete, in other terms, that a vague reference to those "position" papers that we all know, in other terms ;) (and one of those I'd like to discuss in detail...) Maybe James can help here. In practice, we could, for instance, *within the current ABI*, provide a switch to disable completely reference counting, would that be appreciated? I can implement this very quickly but I'd like to have some evidence that a non-trivial number of users would appreciate that short-term solution. That would be indeed, a short term solution, because a library relying purely on a non-refcounted string has subtle issues with memory allocation during exceptions, that definitely we don't want in a long term solution: if nobody has got a better idea, I'm afraid we have to implement also a separate ref-counted mini-string for usage in exceptions. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21334
