[webkit-dev] assertion failure in WTF::StringHasher::createBlobHash at StringHasher.h:146

[Xiaomei Ji]

I've seen the following assertion failure when I start Safari (in debug mode
on my local build). I do not think it is related to my local change. And
I've just deleted the "WebKitBuild" directory and rebuild.
Anyone has any idea on what might be wrong here?

Thanks,
Xiaomei
