Hi! I am using Casr to analyze program crashes found with Sharpfuzz. But the problem is that Casr analyzes stacktraces reproduced by crashes, but the debug-info in target binary disappears after Sharpfuzz instrumentation. For example:
Stacktrace without Sharpfuzz intrumentation:
Unhandled exception. System.ArgumentException: Global tags must be valid URIs. (Parameter 'value')
at YamlDotNet.Core.TagName..ctor(String value) in /YamlDotNet/YamlDotNet/Core/TagName.cs:line 51

Why is it so? And is it possible for Sharpfuzz not to remove this debug-info? It would be really nice, because it makes crash triage pipeline much easier)
