Comment (by tscrim):
Replying to [comment:206 darij]:
> Ohkay, the ncsym issue is simple (one should simply replace the claimed
output by the actual new output), but the unique_representation one is
tricky. Simon??
The NCSym is this ticket (not #15367); see comment:188 and #15150. As for
the unique representations, there seems to be a memory leak. Using the
failing example from #14912:
{{{
sage: import gc
sage: O = SomeClass(1)
creating new instance for argument 1
sage: del O
sage: gc.garbage
[]
sage: gc.collect()
3
sage: O = SomeClass(1)
sage: x = get_memory_usage()
sage: x
176.6640625
sage: L = [SomeClass(i) for i in range(10^6)] # I removed the creation
printing
sage: del L
sage: get_memory_usage()
652.1171875
sage: import gc
sage: gc.collect()
0
sage: get_memory_usage()
652.1171875
}}}
