json-parser.c carefully reports end of input like this: token = parser_context_pop_token(ctxt); if (token == NULL) { parse_error(ctxt, NULL, "premature EOI"); goto out; }
Except parser_context_pop_token() can't return null, it fails its assertion instead. Same for parser_context_peek_token(). Broken in commit 65c0f1e9558, and faithfully preserved in commit 95385fe9ace. Only a latent bug, because the streamer throws away any input that could trigger it. Drop the assertions, so we can fix the streamer in the next commit.
