Closes PR 14059 Symbols in the PR were mapped to coliding hashes in groups of 4 because the low 2 bits of the `eq?` hash code were begin dropped to generate an `equal?` hash code. Those two bits got lost due to a refectoring a while back that moved the dropping of two useless bits to a more centralized place, but the 2-bit shift did not get removed from the `equal` hash code comparision. The PR's example program will still generate groups of 2 when hashing around 10k symbols (which used to be groups of 8). That's because there's a bit in the hash-code counter that turns out to be forced to 1. |
