Predator and CL could not provide any possible suspects. Using Code Search for the file, "url_canon_icu.cc" assigning to the concern owner who might be related. Suspect CL: https://chromium.googlesource.com/chromium/src/+/c5698b5c9d00bc9f9e9960995f6def95c714a41d jshin@ -- Could you please look into the issue. Thank You.

InitializeICU has to be called before using ICU. Apparently, the fuzzer test in question didn't call Init..ICU.

I made a CL ( https://chromium-review.googlesource.com/c/chromium/src/+/912355 ), but realized that Jun Choi did it before me for bug 808412 .
