This is only in tests/, but easy to fix, so...
I've included extra context so you can see how var->value would
be used in the following atoi call.

Subject: [PATCH] avoid use of free'd pointer
* asschk.c (set_type_var): Set var->value to NULL after freeing it,
to avoid subsequent use of freed pointer.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
select returns with -1.
* tools.texi (gpg-connect-agent): New.
* app-openpgp.c (get_one_do): Never try to get a non cacheable
object from the cache.
(get_one_do): Add new arg to return an error code. Changed all
callers.
(do_getattr): Let it return a proper error code.
* app.c (select_application): Return an error code and the
application context in an new arg.
* command.c (open_card): Adjusted for that. Don't use the
fallback if no card is present. Return an error if the card has
been removed without a reset.
(do_reset, cmd_serialno): Clear that error flag.
(TEST_CARD_REMOVAL): New. Use it with all command handlers.
* scdaemon.c (ticker_thread): Termintate if a shutdown is pending.
* apdu.c: Added some PCSC error codes.
(pcsc_error_to_sw): New.
(reset_pcsc_reader, pcsc_get_status, pcsc_send_apdu)
(open_pcsc_reader): Do proper error code mapping.
* gpg-connect-agent.c: New.
* Makefile.am: Add it.
* asschk.c (start_server): Close the parent's file descriptors in
the child.
(read_assuan): Variable NREAD removed. Cut off the received line
currectly if more than one line was read.
