Detected a use-after-free :-) See:

|
Special-cased it too as (it's a well-known race and) i don't see how we could prevent it. |
|
Woah, a well-known use-after free? That's not good! What's happening here? Looks like the cc should be owned by NULL, so that freeing the cmd doesn't destroy it. (we'll still get a memleak if the bcli plugin crashes, but hard to care). |
|
Spent half an hour writing about how i already tried this and this doesn't work, but actually you are right. Pushed a fix and removed the suppression. |
|
(Also for the record by "well-known" i meant the functionality race, so we might have expected the data race: that was nonsensical) |
|
Travis really does not like the 100 nodes of test_funding_cancel_race under ASAN.. |
|
Hmm, if ASAN isn't going in, can you open a PR for the others? Be nice to have them in 0.9.1... |
|
Sure

Trying only on the clang job now (for some reason the gcc ones produce errors..) |

Very nice, it'd be a major improvement to be able to run lightweight sanitizers in production ( However I wonder why the suppressions are located in |
clang did the hard work here:
openingd/dualopend.c:958:42: error: result of comparison of constant 'WIRE_DUAL_OPEN_FAIL' (7003) with expression of type 'u8' (aka 'unsigned char') is always false
[-Werror,-Wtautological-constant-out-of-range-compare]
if ((msg_type = fromwire_peektype(msg)) == WIRE_DUAL_OPEN_FAIL) {

Rebased on #4076 and moved the sanitizers suppressions in contrib/ |

Oh, can we have a Changelog-Added: build: clang build now supports |

Sure, but i doubt that Travis is going to pass anyways :/ (going to wait for it then amend) |

Travis still ooms on |

I'm looking at including some fuzz targets, and will probably use clang along with its address sanitizer (and hopefully many others!).
This removes the restriction on only using gcc with ASAN, by using suppressions instead when using clang (see #2285 for the reason).
This also enables ASAN on non-already-under-valgrind Travis jobs.
