Re: Behaviour changed between 1.1.0 and 1.1.1

I can't reproduce the issue, using latest master for both gost and openssl:

/tmpram/gost > export OPENSSL_ENGINES=/tmpram/gost/engine/bin 
/tmpram/gost > /tmpram/openssl-111-pre9-dev/bin/openssl pkey -engine gost -pubout -text -in tmp.pem
engine "gost" set.

/tmpram/gost > /tmpram/openssl-111-pre9-dev/bin/openssl pkey -engine gost -pubout -text -in a.pem  
engine "gost" set.

Hello,
I use my engine providing gost algorithms (https://github.com/gost-engine/engine). It seems not to have any relevant changes between 1.1.0 and current master, but the command 

OPENSSL_CONF=engine.conf openssl pkey -pubout -text -in tmp.pem

works ok for 1.1.0 version and does not work for current master.
For the file a.pem both versions provide similar output.

engine.conf is minimal conf to load gost engine:
=============
openssl_conf = openssl_def
[openssl_def]
engines = engine_section

[engine_section]
gost = gost_section

[gost_section]
engine_id = gost
dynamic_path = /path/to/libgost.so
default_algorithms = ALL
CRYPT_PARAMS = id-Gost28147-89-CryptoPro-A-ParamSet
===============

I've found out that behavior of the function EC_POINT_get_affine_coordinates_GFp has changed between versions 1.1.0 and current master. 

Also I found that pkey command ignores result of the calls to EVP_PKEY_print_public and EVP_PKEY_print_private.

Could you please clarify whether it's a bug in my engine or something  incompatible in openssl code?

Thank you!
