            Bug ID: 221119
           Summary: [GLIB] Many API tests are asserting in debug mode when
                    destroying WebProcessPool
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: lmoura at igalia.com
                CC: bugs-noreply at webkitgtk.org

About 40 tests are crashing in debug builds with the same trace. For example:

WebKitBuild/WPE/Debug/bin/TestWebKitAPI/WPE/TestConsoleMessage
   /webkit/WebKitConsoleMessage/js-exception

This issue happens when running together with other test cases, as running the test (function, not the program) isolated it works.

Trace:
