SIGABRT during exit() on FreeBSD

[l1gi]

I am still facing this kind of crash:

The process works as expected during its life, just leaves a core after closed. It happens every time I close it. It does not depend on the content of config file.

Let me know how can I assist you to debug this.

Thank you.

I am observing the issue regularly while I quit the process. The trace could look different, I have hit similar issue in add_tag().

I have enabled clang ThreadSanitizer to check whether there is some race condition or mutex issue. This is what I got.

trace.txt

And SIGABRT was at the end.

Please look even into invalid casts: (<unknown>:50063): GLib-GObject-WARNING **: 20:40:08.166: invalid cast from 'InternetAddressGroup' to 'InternetAddressMailbox'

Any hint, please?

Seems like a second main-thread is started? With different logging formatting? Does the same happen if you do not have automatic polling enabled?

Hi Gaute,

sorry for late reply.

Yes, polling disabled, only one window. This is actual trace.
