The name_rev() function's 'tip_name' parameter is a freshly xstrdup()ed string, so when name_rev() invokes: tip_name = xstrfmt("%s^0", tip_name); then the original 'tip_name' string is leaked. Make sure that this string is free()d after it has been used as input for that xstrfmt() call. This only happens when name_rev() is invoked with a tag, i.e. relatively infrequently in a usual repository, so any reduction in memory usage is lost in the noise.
