Parser is converting some numeric values incorrectly

[justjoehere]

Executing the following code
FastJsonparser.parse("[{ \"duration\": 7386425359 }]")

Results in
{ :duration => -1203509233 }

This parsing is resulting in a change in values
7386425359 is being converted to -1203509233

It's like there's a weird conversion from an unsigned to a signed 33 bit conversion taking place. I used this tool to make that guess https://onlinetoolz.net/unsigned-signed#base=10&value=7386425359&bits=33

Hi @justjoehere

Can you confirm this issue on 0.5.0 version ?

[justjoehere]

Still occurs in 0.5.0.

Hi @justjoehere

I added test case to reproduce this issue, 96ff5c5

But test cases is passing.
Can you provide a failing test for this issue ?

[ahorek]

the test is actually failing on platforms where sizeof(long) != 32 like Windows.
