Which in perfetto comes via gn:default_deps

Strange, buffered_frame_deserializer_fuzzer does depend on gn:default_deps already..

Actually, no ASan necessary; it just doesn't build at all:

$ gn gen --args="use_libfuzzer = true" out/release && ninja -C out/release buffered_frame_deserializer_fuzzer

Uh strange. The thing I cannot understand is: how come chromium's build picks up the buffered_frame_deserializer_fuzzer traget.
No chromium GN file depends on that.
I guess gn just builds all target in a GN file if there is at least one dependency to one target to the same gn file.

We should either mask out that target with is_chromium_build or figure out how to make it build in chromium

 Issue 834463  has been merged into this issue.

Marking as fixed as the CL has been reverted.

I am still waiting for this build to come back green, but it probably will soon:
https://ci.chromium.org/buildbot/chromium.clang/ToTLinuxASanLibfuzzer/782

Relanding in https://chromium-review.googlesource.com/c/chromium/src/+/1019619 with DEPDS rolled to a rev of Perfetto which excludes the libfuzzer targets.
