Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/d7ebcbcf5f4b8eeec191a1bb8e68d3b67f6d3b8d (Explicitly add signature and header in minidump fuzzer). If this is incorrect, please remove the owner and apply the Test-Predator-Wrong-CLs label.

Leaks are always bad, but given https://clusterfuzz.com/download?testcase_id=5185524460683264, I can’t find a path in to MinidumpThread::GetContext at all, so I don’t know what to do here. I did prepend the header from https://chromium.googlesource.com/chromium/src/+/d7ebcbcf5f4b8eeec191a1bb8e68d3b67f6d3b8d%5E%21/#F1.
