Description Wander 2022-12-02 14:23:09 UTC

Description of problem:

When running bpftrace in RHEL 9.2, it crashes with the following messages:

[root@dell-r750-02 ~]# bpftrace
: CommandLine Error: Option 'use-dbg-addr' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Aborted (core dumped)


Version-Release number of selected component (if applicable):
0.13.1-1.el9


How reproducible:
Always


Steps to Reproduce:
1. dnf install -y bpftrace
2. bpftrace
3.

Actual results:
Crash dump


Expected results:
The command is to run successfully.

Additional info:
There is an issue in Github that says it is related to llvm being statically linked in both bcc and bpftrace

Comment 1 Viktor Malik 2022-12-05 07:06:03 UTC

I believe that the problem is that bpftrace has not yet been rebased to LLVM 15. I'll do it after the last BPF subsystem rebase is merged, to rebase against correct libbpf.

Comment 2 Carlos Rodriguez-Fernandez 2022-12-13 23:20:48 UTC

Same here.
I started a brand new Centos Stream 9 VM in digitalocean. I did a "dnf up -y", and then installed bpftrace and a simple run shows the same error:

```
$ bpftrace -l
: CommandLine Error: Option 'use-dbg-addr' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Aborted (core dumped)
```

Thank you for working on this Viktor.

bpftrace 0.16.0-1 which supports LLVM 15 is now in the buildroot and the nightly compose, so this bug should not happen anymore.

Wander, Carlos, could you please confirm?

Thanks!

I suppose by tomorrow 9.2 builds will ship it?

Yes, it appeared in the compose yesterday, so it's likely in today's builds, too.

Hi Viktor,
I can confirm that the problem is fixed in Centos 9 Stream.

Thank you!
