+1 same issue here. I'm using Zig 0.15.1 with branch zig-0.15.1 (master branch also doesn't work). I'm on x86_64 linux. Looks like CI caught the issue a few commits ago, but it hasn't been noticed/fixed yet. Last known working version: be8b496

EDIT: Last known working version doesn't have support for zig 0.15.1

[vrischmann]

https://github.com/vrischmann/zig-sqlite-demo works fine with zig 0.15.1; please create a reproducer that I can easily clone and test myself, I can't help you with just this report.

This demo app also fails to compile for me

UPDATE: I found that building with --release=safe (or -Doptimize=ReleaseSafe; also fast release) works as expected. The issue only appears with -Doptimize=Debug

[tadejg]

@vrischmann if it helps, here's a Dockerfile which reproduces the issue.

FROM ubuntu:25.10

RUN apt update && apt install -y ca-certificates git wget xz-utils

ARG ZIG_VERSION="0.15.1"

RUN wget -O /tmp/zig.tar.xz https://ziglang.org/download/${ZIG_VERSION}/zig-x86_64-linux-${ZIG_VERSION}.tar.xz && \
    mkdir -p /opt/zig && tar -xf /tmp/zig.tar.xz -C /opt/zig && \
    echo "export PATH=\"/opt/zig/zig-x86_64-linux-${ZIG_VERSION}:/usr/bin:$$PATH\"" >~/.profile

[enverbisevac]

Yes it works for me too with --release=safe

[tadejg]

@vrischmann I also noticed you switched to dynamic linking for 0.15.1. What was the reasoning behind that? I'd prefer to keep it static, if possible.

[vrischmann]

So, there was no reason to change to dynamic linking, that was an oversight when merging a PR.

But that is not the issue here, executing the zig build-exe command shows zig crashing:

Seems to only affect Linux, on macOS it builds fine.

[tadejg]

Maybe related to ziglang/zig#25060

Adding .use_llvm = true to the demo build.zig seems to work

    ...
    const exe = b.addExecutable(.{
        .name = "zig-sqlite-demo",
        .root_module = exe_mod,
        .use_llvm = true,
    });
    ...

Looks like a bug in the compiler which I can't do much about unfortunately.

Maybe related to ziglang/zig#25060

Adding .use_llvm = true to the demo build.zig seems to work

...
const exe = b.addExecutable(.{
    .name = "zig-sqlite-demo",
    .root_module = exe_mod,
    .use_llvm = true,
});
...

Nice find, the stack trace looks the same.

[enverbisevac]

Thanks @tadejg, @vrischmann , works with .use_llvm = true

Have you reported it to zig? I ran into this error as well, so hopefully reporting could get a fix in the queue.
