Thank you for your report. This is because Info enters an infinite
recursion, due to a feature that if the specified file is actually a
directory, the reader looks into that directory. That is, for
example, "info -f foo" where `foo' is a directory, will look inside
that directory for a file named `foo', recursively.
Here's a patch to solve the problem:
2000-08-21 Eli Zaretskii <[EMAIL PROTECTED]>
* info/filesys.c (info_file_in_path): Reject FILENAME if it is
empty, or ".", or "..".
