            Bug ID: 199572
           Summary: Crashes in NetworkProcess since the DNS cache landed
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK

I've noticed that several tests have started crashing the network process sporadically and all they have in common is that the crashing starts right after the DNS cache was landed. Opening this bug to track this potential regression.

Some stacktraces to exemplify this:

The stacktraces don't tell much at first sight, but since it seems to be happening deep in glib, there might be some memory corruption somewhere, not sure if related to thread-safety issues in the dns cache resolver (or libsoup even?).
