any([magma(True),magma(True)]) produces stack overflow

[Simon Brandhorst]

```

sage: any([magma(True),magma(True)])                                                                                                                                                              
Fatal Python error: _Py_CheckRecursiveCall: Cannot recover from stack overflow.
Python runtime state: initialized

Can anyone reproduce?

This works for me with Sage 9.5 on macOS 10.13.6 (built from scratch). By “works”, I mean I get “True” as a result.
The same holds for sage 8.[3-9].

However, with 9.[0-4], I get the same error you report: a stack explosion, ending with SIGABRT.

It was reported fixed for 9.5, and Volker’s release message for 9.5.beta6 indicates it was included then. And it does not fail for sage 9.5 on my system.

Simon may let us know what config he’s using.

Indeed it was on 9.4. Sorry I forgot to mention that. Thank you.
