Bill,

It would really help if you posted the exact entries you made when the crash occurred along with the 
size/type of the disk or image you are trying to format. There may not be a problem with Format itself.

Most of the memory used by Format is:
          ...
LSN0     rmb   256        LSN0 build buffer
optbuf   rmb   256
numbuf   rmb   32
fdtbuf1  rmb   3
fdtbuf2  rmb   9924
u297E    rmb   451
size     equ   .

Format builds a root directory using the fdt buffers.
