Bug 21599 – std.digest.crc : crc32Of fails with SegFault on array of 4MB or larger

Following code fails with SegFault: ``` module test.main; private __gshared ubyte[4096 * 1024] buffer; int main(string[] args) { import std.digest.crc : crc32Of; ubyte[4] pcrc = buffer.crc32Of(); // SegFault reported here return pcrc[0]; } ``` Tried with DMD 2.095.0 and LDC 1.24.0.

This construct will cause the function to pass fixed length array ubyte[4194304] and construct struct CRC(uint N, ulong P) with N=64u & P=15564440312192434176LU hence stack overflow. Change to dynamic array construct should fix the problem ubyte[4] pcrc = buffer[].crc32Of();
