Does not work on Windows Subsystem for Linux

[abonander]

This is a known issue:

• ASAN doesn't work microsoft/WSL#121
• Issues with ASAN in Windows 10 Ubuntu subsystem google/sanitizers#708

I just figured it'd be a good idea to have some notice here to save other Windows users from having to find the answer themselves. (Maybe add a note to the README as well?)

This is the kind of error message you get:

==6089==Sanitizer CHECK failed: [...]/sanitizer_common/sanitizer_procmaps_linux.cc:57 ((IsOneOf(*current_, 's', 'p'))) != (0) (0, 0)

Not very helpful, but Googling Sanitizer CHECK failed IsOneOf turned up the above issues.

Not much we can do except documenting it.

[abonander]

Yeah, that's the main reason I opened the issue.

@abonander if you want you can try honggfuzz-rs which should work on WSL.

The underlying issue is supposedly resolved now, though one frustrated commentor seems to beg to differ: microsoft/WSL#121 (comment)

I'm not getting the same error anymore, but I'm not getting useful stack backtraces either:

Edit: running in an Ubuntu server VM produces the same output so this probably has nothing to do with WSL.

@PaulGrandperrin Tried honggfuzz-rs but ran into a couple of problems, reported them on the repo.

[abonander]

Works now on WSL, so closing.
