1649062 - Disable the crash reporter for debug fuzzing build

Status: RESOLVED FIXED

(Core :: Fuzzing, enhancement)

Description

[Christian Holler (:decoder)]

We currently have a non-ASan debug fuzzing browser build that we use both for regular browser fuzzing as well as libFuzzer-based fuzzing. In this build, the crash reporter and symbol stripping are enabled which is why libFuzzer is not providing proper symbols. I tried disabling stripping and various other configuration tweaks but found that they all seem to affect what symbols minidump_stackwalk provides us. Overall we decided that we should entirely disable the crash reporter for this build type and solely rely on the UBSan runtime to report crashes.

Once this lands Fuzzfetch will need to be updated to support downloading crashreporter-symbols.zip only for prior builds.
