No, but Chet would know.

Chet only commits snapshots to git and not individual fixes, so it's 
hard to isolate any one fix from the git repo.

Are you sure? I just did a test compile on that same commit with 
'--enable-minimal-config --enable-strict-posix-default --enable-alias' 
and the bug is definitely not there. Then when I back up one commit and 
run 'make' again, the bug appears.
