How to go about > debugging this? I expect it'd require someone with expertise in byte-compiling. It's not clear that it's a bug, other than a minor performance issue. I do see something similar on my system. The following files differed in one comparison I did: cedet/semantic/grammar-wy.elc cedet/semantic/wisent/javat-wy.elc cedet/semantic/wisent/js-wy.elc cedet/semantic/wisent/python-wy.elc cedet/srecode/insert.elc cedet/srecode/srt-wy.elc gnus/auth-source.elc gnus/message.elc gnus/mm-decode.elc org/ob-C.elc progmodes/antlr-mode.elc progmodes/cc-langs.elc progmodes/cc-mode.elc textmodes/rst.elc In one case I looked at it appears to be gensym values, which ought to be OK.
