There is an updated pull request by pullmoll against master on the void-packages repository
https://github.com/pullmoll/void-packages chromium
https://github.com/void-linux/void-packages/pull/29205
[WIP] chromium: update to 89.0.4389.72
+ x86_64 patch set updated, built, tested very cursory and seems to work
+ i686 patch applies w/o change, built, not yet tested
+ x86_64-musl patch set updated, currently bulding, not yet tested
+ ppc64le patch removed for now as nothing applies (already upstreamed? need to check again)
+ opus disabled because the generated shim header opus.h tries to include <opus.h> and fails
+ not sure if libc_malloc.patch is ok, i.e. simply use malloc() instead of __libc_malloc().
+ more to do
[ci skip]

-Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter
-
-DCHECK_NE comparison requires CheckOpValueStr to be defined for the
-type, or providing an output stream operator. A unique_ptr does not
-provide any.
-
-Compilation in GCC is failing in CompositorFrameReporter because of
-this:
-../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
-../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’
-
-Fixed comparing the result of get() method for unique_ptr instead of
-the unique_ptr.

-Bug: 819294
