git repo (nodejs/node) @ 64de66d78888f46c74ba8b8ea18100a9f35a1c7a I was running CFLAGS="-fsanitize=address -fno-sanitize=leak -g3" CXXFLAGS="$CFLAGS" LDFLAGS="-fsanitize=address -fno-sanitize=leak -g3" ASAN_OPTIONS=detect_leaks=0 make test -j 4 platform: Linux t470 4.17.0-2-MANJARO #1 SMP PREEMPT Fri Jun 8 07:13:17 UTC 2018 x86_64 GNU/Linux

I used clang 6.0 as CC/CXX.

During make test, I got a use after free:

bnoordhuis commented 6 years ago

cc @eugeneo @ofrobots - I'm reasonably sure this is caused by freeing the memory of one of the uv_async_t handles prematurely.

At a guess, the signalling from the close callback needs to be delayed until both close callbacks have happened (applies to both node_trace_buffer.cc and node_trace_writer.cc.)

eugeneo commented 6 years ago

I think https://github.com/nodejs/node/pull/21335 should fix it.

Trott commented 5 years ago

21335 was closed without landing. Did an alternative land? Should this be closed?

If this is still a problem, might it be the source of this that comes up in CI on Windows 10:

¯\(ツ)\/¯ This doesn't look like a build issue. It looks like it was an issue with trace events.
