FYI, the incorrect expansion after refresh is an unrelated issue, and a
platform debug bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=212798
However, for this particular scenairo, the GDB debugger could work
around the bug by ordering threads from oldest to newest.
Cheers,
Pawel

I'm sorry, I've made a mistake: it should expand Thread[1], of course.

yes, this works better. But Stack view expands the same
second-from-top frame, whereas it should expand the third (Thread[2]):

Hi,
can you reproduce this, and when it happens, can you press the Refresh button
on the debug view. If things are fixed, can you send the gdbtraces logs?
Thanks
