Hi, just to be sure people notice: there are new (1-2 days max) regressions in libstdc++, caused by compiler changes. See, for example: http://gcc.gnu.org/ml/gcc-testresults/2008-07/msg00824.html I can look a bit more into this in the next days, but again I pretty much exclude this has been caused by library changes, that's why this heads up...
