Current master is unstable: 'invalid pointer' on establishing IMAP connection with TLS

[cobratbq]

I recently tried using current master branch in an attempt to get a recent version of libetpan which includes the CVE fixes that were merged at the end of 2020, i.e. issues #387 and #388, as there is no release version that includes these fixes. The latest master causes a crash due to invalid pointer. This seems to be triggered upon connecting to an IMAP server using TLS.

An issue captured the crash with limited debug information for the Claws-Mail flatpak package when using IMAP. I then decided to go with an earlier commit 80f0f51 which does not exhibit this problem.

It seems that the recent patch series introduced it. I report this such that you are aware that such an issue exists.

Sorry for the late answer. I reverted a couple of commits on master. Could you check if it fixes this crash?
