Could you look at the errors in the log > files and try to sort them by categories. Only the errors... FAIL: obj-c++.dg/torture/strings/string1.mm -O2 -flto -flto-partition=none -fnext-runtime (test for excess errors) FAIL: obj-c++.dg/torture/strings/string1.mm -O2 -flto -fnext-runtime (test for excess errors) are seen on darwin11 with Xcode 4.5.1 (which potentially could be a linker bug so I'll open a radar). The remaining failures are darwin12 only and might represent ABI changes in 10.8 perhaps.
