FYI: today's regressions in libstdc++

[Paolo Carlini]

Hi,

just an heads-up: today 27_io/basic_stringbuf/setbuf/char/4.cc (and the 
wchar_t counterpart) started failing at compile-time at least on x86 and 
x86_64: at -O2 the compiler eats all the available memory.
You can see the issue reported here, for example:

    http://gcc.gnu.org/ml/gcc-testresults/2007-07/msg00073.html

and I'm consistently seeing here too, of course. I also checked that the 
problem doesn't show up at -O0.

Paolo.
