I haven't investigated each commit, but looking at the "svn diff -r218951:218978" a wild guess would be a bug in the rewrite-changes perhaps related to_GLIBCXX_USE_WCHAR_T. If you can't see it on your system, please run the test under valgrind. The .log entries indicate bugs consistent with the previously quoted log entries (i.e. some allocation bug): PASS: 22_locale/locale/cons/6.cc (test for excess errors) core: 4 byte misaligned read to address 0xa2ce236 at 0x45788 program stopped with signal 10 (User defined signal 1). FAIL: 22_locale/locale/cons/6.cc execution test
