2 years ago That's not a crash as such, 0x80000003 is a hard-coded breakpoint, i.e. like a self halt. There are some of these in the debug VM code as hard assertions of things that are assumed to be a problem, or in one or two cases are heuristics rather than hard conditions. These appear as DebugBreak() calls, or the HARDASSERT macro, or int 3 in the assembler code. They might indicate a problem, and they might not.
Are you running a debug build of the VM? There is really little value in working with a debug build most of the time unless you are actually working on the VM code, or are doing a lot of FFI work when it can sometimes help catch memory corruption from writing off the end of buffers a bit sooner. Otherwise I really wouldn't recommend it. I don't use it when I'm working in Smalltalk.
If you are not running a debug VM, then you might still be hitting a debug check from the heap, which will int 3 if it's metadata gets corrupted, e.g. by a buffer overrun as mentioned, or perhaps by writing to free'd memory. It tends to print some debug trace messages when that occurs, which you will see when running under the debugger. So to investigate further, either start your app under the VS debugger (e.g. just change the debug options for the launcher or VM projects in the solution to open jade.exe, and then F5), or Attach to Process from VS when jade.exe is running. You should find that the debug symbols built for the to-go VM .exe will work, even with your deployed app.

** Dolphin Crash Dump Report ***
Using Dolphin f6c4b3895fcc16fd7f58f65a3463c31fe1be35d3 to build a runtime and I get a crash about every hour or two of active use of the runtime. I believe it happens when presenting or dismissing a dialog. Any advice on what to investigate?
