After this change, tcg_ctx->plugin_insn is not reset inconditionnally anymore, but only if one plugin at least is active. When uninstalling the last plugin active, we stopped reinitializing tcg_ctx->plugin_insn, which leads to memory callbacks being emitted. This results in an error as they don't appear in a plugin op sequence as expected. The correct fix is to make sure we reset plugin translation variables after current block translation ends. This way, we can catch any potential misuse of those after a given block, in more than fixing the current bug.
