To confirm, this is on aarch64, correct? I'll see if I can get a machine to test this.

Yes, aarch64.

Couldn't reproduce this issue on my aarch64 machine (Linux 6.16.0-21-qcom-x1e [#21](/bitcoin-bitcoin/21/)-Ubuntu SMP PREEMPT_DYNAMIC Sun Aug 10 00:54:48 UTC 2025 aarch64), running Ubuntu 25.04, systemtap 5.1-4.1 and bpftrace v0.21.2.

Can not reproduce with bpftrace v0.22.1.

Can reproduce with bpftrace v0.23.2 on both aarch64 and x86_64.

Given the reg type unsupported for arg#0 error, I assume it is related to how we read the txid (arg0). I looked into it a bit, but haven't been to get it to work.

The bpftrace script connectblock_benchmark.bt works. It is similar but reads a block hash instead of a txid. However, not the difference between the arg0 of block_connected (8@-2432(%rbp) and e.g. arg0 of utxocache::add (8@%r15). Maybe that's the cause for the reg type unsupported for arg#0 error.
