Thanks for your bug report. Please have a look at the error again, it
indicates that the problem is in line 533 of stl_deque.h, i.e. in
libstdc++ proper. It shouldn't be too difficult to correct this in
your installation of gcc; please send a patch to
gcc-patches@gcc.gnu.org when you found a fix that
works. Alternatively, you could check the latest version of SGI STL,
since g++ always incorporates the SGI code in this area.

Martin
