Predator and CL could not provide any possible suspects. Using Code Search for the file, "partition_alloc.h" suspecting the below Cl might have caused this issue Suspect CL: https://chromium.googlesource.com/chromium/src/+/f369a29a01b3d8e8269afae32157f3e4e7ec7e3f palmer@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner. Thanks!

I don't see anything actionable in this bug report. Running the reproducer tool gets me a very different result:
