            Bug ID: 186382
           Summary: [GTK] Crash running run-webkit-tests
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: cadubentzen at gmail.com
                CC: lforschler at apple.com

All tests are crashing when running `run-webkit-tests --debug --gtk --no-new-test-results --no-retry-failures`.

My platform:
- GCC 8.1
- Arch Linux
- Gnome-shell on Wayland

It ultimately is calling getenv(nullptr) which leads to SIGSEGV.

Truncated backtrace:

Using host libthread_db library "/usr/lib/libthread_db.so.1".
Core was generated by `/home/cadubentzen/git/github/webkit/WebKitBuild/Debug/bin/WebKitTestRunner -'.
Program terminated with signal SIGSEGV, Segmentation fault.
