--- Comment #21 from Arjun Shankar <arjun.is at lostca dot se> ---
I'd like to clarify what exactly was fixed with commit
91927b7c76437db860cd86a7714476b56bb39d07:

The commit fixes the hang that occurs with the following reproducer (comment
0):

> echo -en '\x80' | iconv -f us-ascii -t us-ascii//translit//ignore -c

which is caused by a bug in the iconv front-end's option parsing.

It does not fix the hang that occurs with, e.g., the following reproducer
(comment 2):

> echo -en "\x0e\x0e" | /usr/bin/iconv -c -f IBM1364

This is a converter specific bug and corresponds to bug 26224.
