Or, is it possible to list the last several commits of file lib/maple_tree.c so that I can reproduce it on my side. I guess maybe I can try to reproduce this with: * set CONFIG_FRAM_WARN to 1024 * set KCFLAGS="-O3" I would try to take a look first. Is the GCC version matters? I don't have the exact version at hand. Have you tried other version? -- Wei Yang Help you, Help me
