[issue24605] segmentation fault at asciilib_split_char.lto_priv

[STINNER Victor]

STINNER Victor added the comment:

It looks more like a bug in networkx, than a bug in Python itself. networkx has probably issues with reference counter, concurrency (threads), or things like that.

I'm unable to reproduce the crash on Python 3.4 (system binary from Fedora 22) or Python 3.6 (compiled manually).
