----------------------------------------
I am writing HTM (Hash Table Machine - a C benchmark program for hash table) and libruby aborts with

ruby: [BUG] Segmentation fault at 0x00000000000018
ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]

while attempting to get an entry from an empty hash table.

Attached is a simple program that reproduces the bug.

Hope it helps.

ciao
