gpg-agent crashes on winows importing a secret key
Closed, ResolvedPublic

Description

gpg-agent crashes when I try to import a secret key.

This is on 64-bit Winows 8.1 Enterprise.

The key I'm trying to import is a stripped down version of my key 8213 71DD
4665 CF4F AE20 2206 0424 DC19 B678 A1A9. Specifically, the master key is a
stub, and the ed25519 and nistp384 keys were removed, leaving only dsa2048
and elg2048 subkeys.

Here is the crash result:

After deleting the master key and the ecc keys, I imported it into gnupg
1.4.12, which I then exported it from. This was just to make sure I have a
compatible key.

Here's the output of gpg (1.4.12) -K

bjmgeek set Version to 2.1.4.

I also might add, I cleared out the %appdata%\gnupg directory before trying to
import the key. I also tried importing my public key first, then importing
the secret key, with the same result.

There is a bug in Libgcrypt < 1.6.4 causing a bus error in the AESNI code.
The 2.1.8 installer will come with a fixed libgcrypt.

yes, this was fixed in 2.1.8
