I noticed that we are failing... FAIL: 27_io/ios_base/storage/11584.cc execution test
in the libstdc++ testsuite on i686-apple-darwin9 in gcc 4.3 branch and gcc 4.3.0. However we stopped failing this in gcc trunk by r132965... http://gcc.gnu.org/ml/gcc-testresults/2008-03/msg00427.html and the last recorded failure in gcc trunk was for r132950. This implies that either...
