Yup:
Breakpoint 1, fancy_abort (file=0x82a7f8 "../../gcc-4.0/gcc/stor-layout.c",
line=221,
function=0x82a87c "smallest_mode_for_size") at diagnostic.c:556

line);

5415 + byte *
BITS_PER_UNIT,

FWIW this code was recently changed by this patch:
2005-03-07 Richard Sandiford <[EMAIL PROTECTED]>
PR rtl-optimization/19683
* reload1.c (choose_reload_regs): Pass the number of bits, not the
number of bytes, to smallest_int_for_mode. Fix arguments to
REG_CANNOT_CHANGE_MODE_P.
