I started looking into this, but I must confess I don't know the pprof code very well. It looks like most stacktraces have an abundance of _System in them, which means that the tracing algorithm in runtime/proc.go's sigprof failed and resorted to _System as the final case for putting something down. It's not clear to me why the prior lookups are failing, though.

I'm CCing @nodirt and @ianlancetaylor who seem to have written a lot of this code and might have better intuition than me on it.

FYI, this is not a real fix.

gopherbot pushed a commit that referenced this issue Nov 28, 2020
This is blocking forward progress of the de-bitrotting work, and I don't
know off hand how to fix this. Seeing as its disabled on other
platforms, I suspect pprof might not be a very reliable feature, so just
allow for the tests to fail for now, until somebody more motivated comes
along to fix it.

Updates #42862.

I'm not familiar with the Windows profiling code. That said, I would start by looking at the values passed to sigprof: are they the right PC/SP/LR values? If they are, why is the traceback failing?

I did notice at some point that enabling debugCheckBP fails on windows/amd64. #41995

I don't have windows/arm to test with, but I'm wondering whether it would fail as well and point to the underlying issue?

@zx2c4 you can try setting asyncpreemptoff, like in #42528 (comment) But I am grasping for straw.

Long time ago I would debug these things just by adding println everywhere. You can do that. Make repro as small as you can, and see why it fails.
