Not now by me. If possible publish your input data so that it can
be used for debugging in future.

Here (3,3 MB):

There is an input vector boundaries

x_extr

and the 100m buffer with a visible fault

x_extr_buff100

I deleted my original input and created it once more to prepare this
sample dataset - and somehow now there is only 1 error in the
v.buffer output instead of 2 as previously... Hmm. Maybe my fault.

How do look those 2 places if run with debug=clean?

Topologicaly clean, but the fault in buffer is still clearly visible.
