Segmentation fault

Hi,

Thanks for having this nice library public!
I think I found a bug, or perhaps I stumbled into an undocumented limitation; I was building the suffix
array of a ~1.8GB sequence, as 32 bit integers and got a segmentation fault.

The steps to reproduce it are as follows:

• Change line 10 of file https://github.com/jlabeit/parallel-range-lite/blob/master/demo/main.cpp ,
  from "typedef uint64_t uint_t;" to "typedef uint32_t uint_t;"
• Download the following input file (~300MB, decompress it with 7z).
  https://www.cs.helsinki.fi/u/dvalenzu/tmp/parallel_range_lite/genome_problematic.txt.7z

Then the following happens:

./main.o genome_problematic.txt
Segmentation fault (core dumped)

I don't think it is because of lack of memory, as I am runing this in a server with 1.5TB of ram.
and when I montitored the memory used I got the following:

/usr/bin/time --verbose ./main.o /home/scratch-ssd/dvalenzu/Data/genome_problematic.txt
(...)
Maximum resident set size (kbytes): 30819104

Best,
Daniel

Compliation problem

While trying to compile I have an error

Any suggestion to get pass this error?
