Description

I've faced a critical error in the log after upgrade to 5.5 on topos module.

Troubleshooting

It looks like ki_tps_set_context() tries to free incorrectly defined variable _tps_context_value.

Reproduction

loadmodule "topos.so"
modparam("topos", "storage", "db")
modparam("topos", "db_url", DBURL_PRIMARY)
modparam("topos", "sanity_checks", 1)
modparam("topos", "branch_expire", 300)
modparam("topos", "dialog_expire", 7200)
modparam("topos", "clean_interval", 120)
