Additional information

We suspect it is the same check/comment

node/deps/v8/src/base/platform/platform-aix.cc

Lines 194 to 199 in 5b6091c

	// If this check fails it's most likely due to a racing condition where
	// another thread has mapped the same address right before we do.
	// Since this could cause hard-to-debug issues, potentially with security
	// impact, and we can't recover from this, the best we can do is abort the
	// process.
	CHECK_EQ(ptr, address);

WPTs can be marked as flaky but that's not helpful if the whole test file crashes. Using #62517 we can now skip a subtest if it can be isolated by name. When the status file is cjs it can be skipped conditionally on aix only.
