One possible culprit is working with detached HEAD, are you pushing with
detached HEAD?
"current_branch" is allowed to be NULL when HEAD does not point to a
branch. From read_config():
if (startup_info->have_repository) {
const char *head_ref = refs_resolve_ref_unsafe(
get_main_ref_store(repo), "HEAD", 0, NULL, &flag);
if (head_ref && (flag & REF_ISSYMREF) &&
skip_prefix(head_ref, "refs/heads/", &head_ref)) {
repo->remote_state->current_branch = make_branch(
repo->remote_state, head_ref, strlen(head_ref));
}
}
This condition fails in detached head and "current_branch" is not set:
head_ref && (flag & REF_ISSYMREF) && skip_prefix(head_ref, "refs/heads/", &head_ref)
>> The direct culprit is this part:

To work with branch = NULL, it seems obvious that branch should be
conditionally dereferenced in pushremote_for_branch, i.e.
- if (branch->remote_state->pushremote_name) {
+ if (brnach && branch->remote_state->pushremote_name) {
However, if you are not using detached HEAD, the problem might be
elsewhere..
