Description

Sometimes my miner crashes while mining C31 on CPU with the following message:

"...cuckoo/cuckatoo/mean.hpp:939: void edgetrimmer::trimrename1(u32, u32) [with bool TRIMONV = true; u32 = unsigned int]: Assertion `renames < buckets[NX][NY].renameu1' failed.

Aborted (core dumped)"

Contributor guide

Research direction
Inspect the assertion in mean.hpp:939 and trace the rename1 function to understand why renames >= buckets[NX][NY].renameu1.
