+Subject: [PATCH] tests: don't run buf::oom on 32-bit systems
+
+On a 32-bit Linux systems, the value large enough to make malloc
+guarantee a failure is also large enough that valgrind considers it
+"fishy".  Skip this test on those systems entirely.
+
+(cherry picked from commit 415a8ae9c9b6ac18f0524b6af8e58408b426457d)
