segfault on variable reuse

[rgaudin]

Reusing the same variable for different Creator segfaults

In [1]: import libzim.writer

In [2]: c = libzim.writer.Creator("/data/test03.zim", "/A/index.html", "fra", 2048)
/data/test03.zim

In [3]: c = libzim.writer.Creator("/data/test04.zim", "/A/index.html", "fra", 2048)
/data/test04.zim

In [4]: Segmentation fault

I cannot reproduce.

Maybe not the root of the bug but the correct usage is with a context manager :

import libzim.writer
with libzim.writer.Creator("/data/test03.zim", "/A/index.html", "fra", 2048) as c:
    pass
with libzim.writer.Creator("/data/test04.zim", "/A/index.html", "fra", 2048) as c:
    pass

(Or you have to call finalize, but I prefer to advocate for the context manager).

Yes, it's the finalize bug we reported a while back.

I agree it doesn't make much sense to reuse a variable on an unfinalized Creator but nevertheless, it shouldn't crash the runtime :)
