This was a bug. In src/system/sys-common.c there is
  #define Max_Nsize 20000000
that you can change to
  #define Max_Nsize 50000000

5e7 is about the limit, since we need to be able to fit the cons cells in
2Gb of memory.

Under the new memory manager in 1.2 this is unnecessary, as you don't need
to specifiy a --nsize or --vsize.
