Hello,
I created this bug as a tracker of various issues, that emerged from use of GCC 7 instead of GCC 6.3

1) I wanted to use debug build, but it FTBFS because of compile time error.

error: 'fts_ast_node_type_get' was not declared in this scope

and simmilar, the build log can be found here

2) When built with GCC7, about 120 new tests start to fail.

To check, if it is caused by GCC, I made 2 containers in which I tried to get as close to Fedora Koji build system machines, as possible. Those 2 containers then differ only in version of GCC and its dependecies.

I attached list of packages, build logs and lists of failing tests from both containers.

• files with '_gcc' are after GCC7 upgrade
• failing tests list from 'fail_docker_25' are long term failing, I don't need to solve them now.

The source RPM, that I rebuilt, can be found here
