in the context of Reproducible Builds, we noticed that eztrace can't
reliably be built because it (can?) generate very huge files that fills
the entire file system (and we have a 200GB file system).

That means a ~200GB file got written (actually is still getting
written), then removed but the process keeping it open (for writing) is
This is the 3rd time I have to kill extrace after having messed up with
our builders (and now I'm going to blacklist it from testing...).
That's not the only file, the other day I noticed that after killing
those 2 processes keeping that file opened 2 other started growing very
fast (like 1GB every 30 seconds), and in very little time they reached
I noticed this only happens in amd64, not in armhf, I believe this is
some kind of issue with highly parallelized builds, since we build with
Furthermore the tests are not considered in the build process, so they
are actually completely useless, so I even wonder what's the whole point
on running them...

Thanks for maintaining eztrace.
