442569 - LME reports a transient memory leak when closing Message (only) window

Status: RESOLVED INCOMPLETE

(Thunderbird :: Mail Window Front End, defect)

Description

[Serge Gautherie (:sgautherie)]

This is with my usual profile,
or dumb Pop3 or Imap4 account profiles.

Moving here from bug 365723 comment 11,
as Unconfirmed until I narrow the (profile) triggering cause.

NB:
Leak Monitor extension v0.4.2 reports Leak + Reclaim.
I'd like to avoid this annoyance,
but it's not an actual memory leak otherwise.

1. Open a message in its own window.
2. Ctrl+W (Close Message window), or Alt+F4.
2r. Wait a little, then get leak (and later reclaim):

SM has the same <charsetOverlay.js> as TB, plus the 2 others.


These may yet be related (= showing in) to TB bug 442478 and SM bug 442478.

Fwiw, this is not bug 438927, which was already checked in.

Yes, I said only that its patch was checked in.

Patch in bug 456860 has been waiting for review for 8 months!
I have not looked at this (and related) bug(s) since then :-<
