Updated to binutils-2.14.90.0.8 and tried the gcc-4.1.2 sources...
The result was a similar crash during newlib build :

../../../../../../newlib/libc/stdio/vfwscanf.c: In function '__svfwscanf_r':
../../../../../../newlib/libc/stdio/vfwscanf.c:1454: error: insn does 
not satisfy its constraints:
(insn 5720 5718 5721 500 (set (reg:HI 2 y)
        (plus:HI (reg:HI 0 x)
            (const_int 21 [0x15]))) 52 {*addhi3} (nil)
    (nil))
../../../../../../newlib/libc/stdio/vfwscanf.c:1454: internal compiler 
error: in reload_cse_simplify_operands, at postreload.c:393

Ok, if one doesn't need a standard C library like newlib, the GCC (and
libgcc with it) builds should succeed up to gcc-4.2.4, in gcc-4.3.x the
libgcc build may crash...
