Tab completion in ipython causes SIGABRT

[simon-b]

Appears similar to but distinct from #134
Coincidentally, here ipython terminates with exit code 134.

Running:
> ipython

from cylp.cy import CyClpSimplex

s = CyClpSimplex()
s.  # Press TAB

Output:
ClpSimplexPrimal or ClpSimplexDual must have been called with correct startFinishOption
<exit code 134>

Note that I do NOT see this in a regular python REPL; only with ipython.

Here running on an ARM mac:
Python 3.12.4
cylp==0.92.3
numpy==1.26.4

In case it's useful, lldb:

> lldb python
ru(lldb) target create "python"
Current executable set to '/.../bin/python' (arm64).
(lldb) run -c 'from IPython import start_ipython; start_ipython()'
