Subject: QuickJS: fix fs callback return value leak
X-Git-Url: https://git.kaiwu.me/?a=commitdiff_plain;h=592ee994670c6a3ca5db280cc3db7d20a9ccb83a;p=njs.git

QuickJS: fix fs callback return value leak

Previously, the value returned by a callback passed to the callback
flavor of fs functions was never freed.  The value stayed referenced
until the runtime was freed, triggering the
"list_empty(&rt->gc_obj_list)" assertion in JS_FreeRuntime() in debug
builds and accumulating in the runtime with js_context_reuse.

The issue was introduced in 1f8f9992 (0.8.9).
