Package: bpftrace
Version: 0.11.3-3
Severity: grave
Justification: renders package unusable
Any attempt of running bpftrace programs fails on my sid workstation:
$ sudo bpftrace -e 'kprobe:do_nanosleep { printf("PID %d sleeping\n", pid); }'
Two passes with the same argument (-tti) attempted to be registered!
Segmentation fault
The issue isn't limited to kprobes, uprobes fail too:
$ sudo bpftrace -e 'uprobe:/bin/bash:readline { printf("Hello\n") }'
Two passes with the same argument (-tti) attempted to be registered!
Segmentation fault
Even bpftrace -V fails, though with a different error:
$ sudo bpftrace -V
bpftrace v0.11.3
free(): double free detected in tcache 2
Aborted
I'm running linux-image-5.9.0-4-amd64 5.9.11-1 and libllvm11
1:11.0.0-5+b1.
