Bitshift when calling C function

[StamesJames]

I tried the template and noticed that the integer returned by the C function get_n is 1092 but the integer that is getting printed by the CallC Vernacular command is 546.
For me it seams that at some point there happens a bitshift to the right because for the following other integers I get the following other prints:
return 1093 prints 546
return 1094 prints 547
return 0 prints 0
return -1 prints 2147483647
return -2 prints 2147483647
return -3 prints 2147483646
because I can't find any reason for this in the code I thought I write an Issue for this.
