Refresh upon hitting a breakpoint sounds like a DSF-GDB bug. Unless:
there actually is a manual refresh mode for threads in DSF. To select
it, you need to enable the "Debug Update Modes" action set from the Window->Customize
Perspective dialog, then go to the Debug view's view menu and look
in the Threads Update Modes sub menu. The mode is Automatic by
default, but it won't hurt to double-check, since the behavior you're
seeing is as if the update mode was manual. Cheers, Pawel Dmitry Smirnov wrote: What about refresh upon hitting a breakpoint? Is it a separate issue or the same platform debug bug? 2009/3/24 Pawel Piech <pawel.piech@xxxxxxxxxxxxx>: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.
