Segmentation fault in RecSplit

[jnalanko]

Hello,

I have the following code:

#include "sux/function/RecSplit.hpp"

using namespace sux::function;

int main() {
	vector<hash128_t> keys;
	for (int i = 0; i < 10000; i++) {
		keys.push_back(hash128_t(0, i));
	}
	RecSplit<8> RS(keys, 100);
}

Compiled with g++ -std=c++17, this crashes with a segmentation fault. If the loop goes up to only 1000, it works. Why is that? Thanks.

Please read the docs.

/** 128-bit hashes.
*

• In the construction of RecSplit, keys are replaced with instances
• of this class using SpookyHash, first thing.
• Moreover, it is possible to build and query RecSplit instances using 128-bit
• random hashes only (mainly for benchmarking purposes).

Sorry and thank you!
