We're seeing sporadic crashes with the following stacktrace:

When I inspect this, it looks like it's pointing to garbage memory:

Unfortunately, I don't have more details about how to repro this as it appears to happen sporadically when running the .NET tests - while it happens consistently on my machine, it doesn't appear to be triggered by a specific test.

This may be related to #6052 as the workaround of introducing a 1s delay for all our tests seems to make it go away happen less often.

Hi, sorry for the delay here. I just haven't gotten around to looking at this yet - haven't forgotten about it though.

I think this should fix the issue, if what is going wrong is actually what's going wrong #6129? If this is happening consistently on your machine, can you test with that branch and see if its fixed there?

I ran the tests a couple of times and I don't see the issue anymore! It was sporadic, but it would almost certainly happen in a full test run, so while I'm not 100% certain, I'm fairly confident the fix works.

    <summary>Package name: <b>realm</b></summary>
    <ul>
      <li>
<b>11.5.0</b> - <a
href="https://snyk.io/redirect/github/realm/realm-js/releases/tag/v11.5.0">2023-02-19</a></br><h3>Deprecations</h3>
<ul>
<li>The ECMAScript Array APIs (such as <code>map</code>,
<code>every</code>, access using indexing operator <code>[]</code>,
etc.) on the <code>SubscriptionSet</code> types were deprecated.
<ul>
<li>The existing methods will continue to work until the next major
version.</li>
<li>The following will <strong>not</strong> be removed from
<code>BaseSubscriptionSet</code>:
<ul>
<li>Being iterable (e.g using <code>for-of</code> loop).</li>
<li>Being able to spread (e.g.
<code>[...realm.subscriptions]</code>).</li>
</ul>
</li>
</ul>
</li>
</ul>
<h3>Enhancements</h3>
<ul>
<li>Converting flexible sync Realms to bundled and local Realms is now
supported. (<a

data-hovercard-url="/realm/realm-core/pull/6076/hovercard">realm/realm-core#6076</a>)</li>
<li>For client reset mode <code>onRecoveryOrDiscard</code>, the
<code>onDiscard</code> and <code>onRecovery</code> callbacks now have
simple default values. (<a

<h3>Fixed</h3>
<ul>
<li>Fixed possible segfault in sync client where async callback was
using object after being deallocated. (<a

since v10.19.5)</li>
<li>If <code>path</code> is defined in the configuration, it will used
for synced Realms too. Relative paths will be appended to a default
prefix (prefix is computed using app id and user id). Absolute paths are
left untouched. (since v10.0.0)</li>
<li>Fixed a bug related to parsing the client reset configuration. (<a

data-hovercard-type="pull_request"
data-hovercard-url="/realm/realm-core/pull/6258/hovercard">realm/realm-core#6258</a>,
since v6.1.0)</li>
<li>When client reset with recovery is used and the recovery does not
actually result in any new local commits, the sync client may have
gotten stuck in a cycle with a <code>A fatal error occured during client
reset: 'A previous 'Recovery' mode reset from &lt;timestamp&gt; did not
succeed, giving up on 'Recovery' mode to prevent a cycle'</code> error
message. (<a

while the "fresh" Realm is being downloaded, the sync client may crash
with a <code>MultipleSyncAgents</code> exception (<a
