Several issues when debugging preview 6 dump #2375
Description
cc @davidfowl
I was tracking down an issue in .NET 6 preview 6 bits and ran into several issues:
System: Ubuntu 18.04
Runtime Version: 6.0.0-preview.6.21316.6
Dotnet dump/SOS version: 5.0.227602+f3ffe27acd2739518d359da0284ae6bf9e9e7966
- We have the images, the PDBs, and it's a dump with heap created by createdump, but all ASP modules can't resolve module names.
dumpasynccrashes dotnet-dump/lldb plugin - and this is likely a DAC bug. This is the relevant bit of the stak:
