State-Changed-Why:
    A minimal testcase is this (just this one line):
    -------------------------
    int i = (0b11111000 == 0);
    -------------------------
    It crashes both the C and C++ front ends with a SegFault.
    This is a regression from gcc3.2 that happens both on
    the 3.3 branch as well as on the mainline. It also happens
    on x86-Linux, not only the win-x-avr crosscompiler for which
    the report initially was.

    The crash for me:
    tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/gcc x.c
    x.c:1:9: invalid suffix "b11111000" on integer constant
    x.c:1: internal compiler error: Segmentation fault
