The latest arm64/aarch64 variant works, though:

The binary of architecture x86_64 is built using clang and statically linked with the glibc of the host on debian:latest (currently bookworm). Binaries for other architectures are built using qbt-musl-cross-make and linked with the musl libc, so that they work properly.

Unfortunately, I have modified the script so that all architectures will be built using clang in the next release, except for mips and i686.

Additionally, I have not been able to reproduce the issue.

It seems it's the same issue as this one. https://github.com/rust-lang/libc/issues/2054

I will build a binary of x86_64 using qbt-musl-cross-make.

Thanks a lot! In the meantime, I reran the above test on multiple Ubuntu 20.04 hosts; it only failed on the first one shown above (which uses an Intel(R) Core(TM) i7-8705G CPU), while servers (using Intel(R) Xeon(R) Gold 6140, 6230 / AMD EPYC 7702P CPUs and the very same set of libc6* packages) don't have the problem.

EDIT: I managed to reproduce the problem on another Ubuntu 20.04 machine–apparently, it's not related to the CPU model, but the kernel version. Using 5.4.x kernels, the above error message is displayed; with kernels 5.15.x or newer ("HWE kernel"), everything works fine.

[travislee89]

I freshly installed Ubuntu 20.04.6 with kernel 5.4, it works fine. It seems that does not relate to the kernel.

On another server works too.

A build using qbt-musl-cross-make on alpine:latest is running, you can download the binaries on the following page after it is done, it might take about 1.5 hours. https://github.com/stunnel/static-curl/actions/runs/7827517597

It seems that does not relate to the kernel.

Pity. Is at least one of the above servers an Intel machine? (The only two machines available using different 5.4.x kernels on Ubuntu 20.04 and that fail for me have an i7-8705G and a Xeon(R) Gold 6230 CPU, respectively.)

I verified that the x86_64/amd64 binary in the attached .zip archive works on both machines, thanks again!

[travislee89]

AMD EPYC 7601(Linode) and Intel Core i7-9750H(VM on MacBook).

For the next release, I'll be releasing two versions, glibc and musl libc.

[travislee89]

Test passed. Next build will compile and distribute both glibc and musl binaries. https://github.com/stunnel/static-curl/actions/runs/7890892806

[travislee89]

FYI @m-ueberall The latest release already includes a version of musl. https://github.com/stunnel/static-curl/releases/tag/8.6.0-1
