<pre>When I try to run an ASan build of Firefox on Windows 11 Beta (version
10.0.22000.1), it crashes with a 0xc0000142 (STATUS_DLL_INIT_FAILED) error. I
filed Firefox bug <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1723593">https://bugzilla.mozilla.org/show_bug.cgi?id=1723593</a>
The crash happens in Clang's runtime clang_rt.asan_dynamic-x86_64.dll here:
