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