--------
I attach here both the text file and the dumped core file.
It's reproducible 100% of times.

It's a text file included into the "angband spoilers" archive.

I found out that adding a (missing) trailing newline in the file will not cause the core dump.
Anyway, it is a bug, as text files don'tr need to have a trailing newline.
