Dump and Minidump Support

Hello Tom,

There is such an option, but, unfortunately, it is not documented. There are the related issues on our tracker:

RIDER-112811 No documentation about how to debug native core dumps

RIDER-112812 No obvious way to debug native core dump.

You need to create a “Native Core Dump Debug” run configuration from Run | Edit Configurations:

Hope that helps. Have a nice day!

What I can observe is that this is very flaky even when the symbols are directly next to the executable, there is a symbol server etc. There seems be be an issue with loading symbols. The new Modules Window in rider 24 is really helpful but also shows that sometimes absolutely no symbols are loaded.
Is there a way to manually load in symbols?

In the Modules tab, right-click on the module missing symbols and load the symbols manually. 

Hi!

I'm trying to follow your instructions, but the Load Symbols option is not available if I right click:

This is a Unity project instead of an Unreal project, but I doubt that should make a difference?

Thank you for your feedback. Apologies for the confusion made. The “Load Symbols” action is only available in .Net debugger.

Due to LLDB (the debugger Rider uses for native apps debug) limitations, there is yet no way to load symbols during the debugging session. In fact LLDB looks for symbols for any .dll loaded at the moment of debugging start (or core dump debug). It searches for .pdb next to .dll and among symbol servers configured. When no .pdb is found, it is missing and there is yet no way to load a missing .pdb.

We do plan to implement several improvements for symbols loading in native debugger including:

• RIDER-127118 Support "Load Symbols" action during native debugging;
• RIDER-117696 Allow choosing modules for which to load symbols;
• RIDER-126540 Not to show disassembly in case of Engine crash when debugging Game target;
• RIDER-63686 Show pdb not found tab when pdb not found during debug;
• RIDER-86981 Allow specifying pdb files to use when attaching to a process.;
• CPP-30215 Speedup debugging by reducing the number of symbol files loaded;
• RIDER-75239 How can I close Unreal Engine not hit disassembly files?;

It is on our roadmap, but, I can't share any ETA at this time.

Thank you for your question!
