This makes 27_io/basic_istream/extractors_character/char/9826.cc fail
(see e.g. http://gcc.gnu.org/ml/gcc-testresults/2005-01/msg01098.html). I'll
attach a semi-reduced test case. Doesn't seem to happen on other platforms.

Profiling shows prominently "alpha_sa_mask" and "reload". Adding -da makes the
problem go away...
