@mmitche do you have any idea of what's going on here? We're getting this failure across many insertion PRs.

Yeah, seemed odd I noticed...I'm looking into it.

Looks like it's only happening in the Linux legs. It doesn't appear to be the same error as the other insertions. Could potentially be a runtime bug? @jeffschwMSFT do you have someone who could take a look at this?

@vitek-karas @elinor-fung @janvorli

mmitche · 2020-04-01T18:10:49Z

Also seen in p3 #7005

janvorli · 2020-04-01T19:06:58Z

It looks like a native heap corruption. Maybe it would be worth trying to run dotnet with Valgrind to see if it catches something.

janvorli · 2020-04-01T19:07:16Z

Btw, is there a core dump available for that crash?

janvorli · 2020-04-01T20:02:50Z

I was able to repro it locally. Here is a stack trace from a local core dump that has more detail on what was running.

I've tried valgrind, it seems to have found some invalid memory write in CorUnix::InternalSetThreadDescription, which was added recently. I am looking into that.

janvorli · 2020-04-01T20:38:42Z

I've found the issue, it is here:
https://github.com/dotnet/runtime/blob/a7f3efbc0f17653ae9b17688e8c94a549b141bcd/src/coreclr/src/pal/src/thread/thread.cpp#L1667-L1669
It happens when the namesize was <= 15, so we'd allocate just <= 15 bytes and then write to the 16th one that's behind the end of the allocated area.

janvorli · 2020-04-01T20:43:10Z

Valgrind rocks, it gave me the answer on a silver plate. See how it showed me where in the code the invalid write happened and then it showed me where was the block of memory behind which we've written allocated:

@janvorli Awesome! Can you prepare a fix for both master and preview3

janvorli · 2020-04-01T21:03:20Z

I am just working on the master one.

akoeplinger · 2020-04-05T14:38:28Z

Looks like this already went in with the auto-merge of #7018 which included the fixed runtime build.

sfoslund · 2020-04-05T18:34:37Z

Yup, closing this one in favor of #7018

mmitche · 2020-04-06T14:27:53Z

We think the duplicated master branch dependency PRs have something to do with the rename of the repo.
