It's 3.4.1 and I did use it as below:

That's the latest version.
Can you get a backtrace? (start "gdb nettle-pbkdf2", at the gdb prompt
I don't know how to use nettle-pbkdf2 actually and it didn't return
when I run as below:
# nettle-pbkdf2 -i 1 -l 16 salt
Sorry, it wants to read the input password on stdin. Try echo foo >
/tmp/foo, and then start it in gdb as
run nettle-pbkdf2 -i 1 -l 16 salt < /tmp/foo
# echo -n passwd|nettle-pbkdf2 -i 1 -l 16 salt

What kind of machine, operating system, and compiler are you using?
Since the testsuite passes on the test systems (including x86_64 and
