Ah! The path from cmd_rebase__interactive! A simple workaround could be:

diff --git a/builtin/rebase.c b/builtin/rebase.c
index c55957c31f..afe376c3fe 100644
--- a/builtin/rebase.c
+++ b/builtin/rebase.c

                        builtin_rebase_interactive_usage, PARSE_OPT_KEEP_ARGV0);

+       opts.strategy_opts = xstrdup_or_null(opts.strategy_opts);

        if (!is_null_oid(&squash_onto))
