[boost] [range] sub_range of istream_range

I’m trying to iterate through a file using sub_ranges of an istream_range
of an ifstream.

However, it seems if I construct sub ranges of various subsets of the full
istream_range, try to adjust the limits with advance_begin and advance_end,
and then access them I get null dereferences. Any thoughts? I can produce
an example if needed.

Cheers!
