crash running example

[progman1]

hello,

In starting methol without a ctf file argument this is printed:

021-10-07T04:33:15.136Z WARN  charts::data::watcher > running on legacy memthol dump format
 2021-10-07T04:33:15.136Z WARN  charts::data::watcher > this will probably not work with this version of memthol
 2021-10-07T04:33:15.136Z WARN  charts::data::watcher > unless the diffs must verify the following invariant:

 2021-10-07T04:33:15.136Z WARN  charts::data::watcher > meaning successive UIDs `uid_i` and `uid_j` must be such that `uid_j == uid_i + 1`

this is from a new build from the repo. is it relevant to:?:
