Description Alex Rønne Petersen 2017-07-13 22:53:49 UTC
I added some debugging code to MONO_PROFILER_RAISE and got this:

> jit_chunk_created raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded
> jit_code_buffer raised before a profiler was loaded

We should see what we can do about that. We might need to initialize the profiler earlier, if possible.
