Null reference in JITCompilationFinished

[noahfalk]

@sillyousu reported a crash in the profiler in thread #4033 - I am creating a new issue for that discussion here.

My suggestion to investigate this is either to manually map the disassembly to source, or to build your own coreclr with symbols so the debugger will do it for you. The function where it failed is fairly small so if you are familiar with disassembly it shouldn't be too bad:
https://github.com/dotnet/coreclr/blob/67a66156d0307b49522a13618522d289268bc1f9/src/vm/eetoprofinterfaceimpl.cpp#L3184

That will narrow the issue from the method to the particular operation that encountered the NULL.

Thank you for your suggestion. I will do more investigation in next few day. 2017-11-15 10:48 GMT+08:00 Noah Falk <notifications@github.com>:

I believe it's a bug in our profiler.

Cleaning up old issues, this one appears resolved.
