That is a known problem which was discussed on gcc lists
in late 2004 but actually dates back to 2000:
http://gcc.gnu.org/ml/gcc/2004-12/msg00126.html
It is in the bug database:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=12245
but has not been solved despite the promises, although
there is a tentative (not actually finished) patch:
http://gcc.gnu.org/ml/gcc-patches/2005-10/msg00091.html
In other words, don't hold your breath. It seems that
most GCC developers think that 1GB is a ridiculously
small amount of memory these days :-(
