Segfault with gpg 1.2.1
Hello ! This is a bug report I sent to the gnupg people, but I thought
you might be interested, since this happens on powerpc unstable and
can't be reproduced on i386.
I get segfaults when trying to sign/encrypt any file with a given set
of options (the one used by emacs mailcrypt).
gdb says :
(gdb) run
Starting program: gpg --recipient "******@laposte.net" --local-user 0x654271E957D752AD --sign --comment 'Processed by Mailcrypt gpg <http://mailcrypt.sourceforge.net/>' --armor --textmode --always-trust --encrypt ~/try.txt
