Source: libtracefs
Version: 1.3.0-1
Severity: serious
Tags: ftbfs upstream patch
Justification: fails to build from source (but built successfully in the past)

Dear Maintainer,

the upstream version 1.3.0 has a race condition in the src/Makefile,
which breaks the build sporadically (when building on a machine with
many cores).

A patch is already available upstream [1].
Reproducing this manually is really tricky, but we consistently see it
on nightly builds with sbuilder.

Best regards,
