samba - Mar 2019 - samba-tool domain provision stuck when using python3

Hello, everyone. 
    I am testing  samba 4.10RC4's the compatibility with python3. I compiled
samba 4.10rc4 successfully in CentOS7.6 with Python3.6.6. but when I run
samba-tool domain provision --use-rfc2307 --interactive
It stuck and did not give any error messages.
then I enable debug
samba-tool domain provision --use-rfc2307 --interactive -d7
it throw info like：
INFO: Current debug levels: all: 7 tdb: 7 printdrivers: 7 lanman: 7 smb: 7
rpc_parse: 7 rpc_srv: 7 rpc_cli: 7 passdb: 7 sam: 7 auth: 7 winbind: 7 vfs: 7
idmap: 7 quota: 7 acls: 7 locking: 7 msdfs: 7 dmapi: 7 registry: 7 scavenger: 7
dns: 7 ldb: 7 tevent: 7 auth_audit: 7 auth_json_audit: 7 kerberos: 7 drs_repl: 7
smb2: 7 smb2_credits: 7 dsdb_audit: 7 dsdb_json_audit: 7 dsdb_password_audit: 7
dsdb_password_json_audit: 7 dsdb_transaction_audit: 7
dsdb_transaction_json_audit: 7 dsdb_group_audit: 7 dsdb_group_json_audit: 7

and it didn't go on.

here's my step to complile samba 4.10rc4.
1 install some packages from repos with epel enabled.
yum install attr bind-utils docbook-style-xsl gcc gdb krb5-workstation \
libxslt perl perl-ExtUtils-MakeMaker lmdb-devel libarchive-devel \
perl-Parse-Yapp perl-Test-Base pkgconfig  libtasn1-tools \
gnutls-devel gpgme-devel jansson-devel libattr-devel keyutils-libs-devel \
libacl-devel libaio-devel libblkid-devel libxml2-devel openldap-devel \
pam-devel popt-devel readline-devel zlib-devel systemd-devel \
python36-devel python36-pip python36-requests
# the python36 packages are in the epel repo.

2 install some python packages as there're no these packages in the repo
(python36 version).
pip3.6 install crypto pygpgme

3 compile samba.
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
--libdir=/usr/lib64 \
--enable-fhs --with-lockdir=/var/lib/samba/lock --with-cachedir=/var/lib/samba \
--with-piddir=/run --with-gpgme --with-systemd --disable-cups
--systemd-install-services
# there's no errors during the compilation process.

4 domain provision
samba-tool domain provision --use-rfc2307 --interactive

it just stuck but did not throw any error.

And when I compile samba 4.10RC4 with python2.7. everything is OK.

could you give any professional suggestion ? thanks.

Thanks for letting us know.

I've filed https://bugzilla.samba.org/show_bug.cgi?id=13828 and 
prepared a merge request with a fix here: 
https://gitlab.com/samba-team/samba/merge_requests/288

I'm also happy to credit you by name if you like, just let me know
before this is merged and I'll amend the commit.

Thank you so much for testing Samba!
