langref: error return trace examples have regressed on master

[mlugg]

Zig Version

N/A

Steps to Reproduce and Observed Behavior

See examples under https://ziglang.org/documentation/master/#Error-Return-Traces. Source locations have been lost in the error return traces:

$ zig build-exe error_return_trace.zig
$ ./error_return_trace
error: PermissionDenied
???:?:?: 0x21dc78 in bang1 (error_return_trace)
???:?:?: 0x21dd83 in baz (error_return_trace)
???:?:?: 0x21dda8 in bang2 (error_return_trace)
???:?:?: 0x21de13 in hello (error_return_trace)
???:?:?: 0x21dee0 in bar (error_return_trace)
???:?:?: 0x21dfb0 in foo (error_return_trace)
???:?:?: 0x21e008 in main (error_return_trace)

I'm unsure whether this is a compiler regression, or if we're doing something wrong when running the code to generate the langref.

Expected Behavior

The error return traces in this section should display line numbers and contents, as in the 0.11.0 docs: https://ziglang.org/documentation/0.11.0/#Error-Return-Traces

did #17503 fix this?

[mlugg]

Ah, probably, thanks for flagging that up! I'll wait til the new builds hit the site, and close this if it's fixed.

Works again:

$ zig build-exe error_return_trace.zig
$ ./error_return_trace
error: PermissionDenied
/home/ci/actions-runner/_work/zig-bootstrap/zig/docgen_tmp/error_return_trace.zig:34:5: 0x21e378 in bang1 (error_return_trace)
    return error.FileNotFound;
    ^
/home/ci/actions-runner/_work/zig-bootstrap/zig/docgen_tmp/error_return_trace.zig:22:5: 0x21e483 in baz (error_return_trace)
    try bang1();
    ^
/home/ci/actions-runner/_work/zig-bootstrap/zig/docgen_tmp/error_return_trace.zig:38:5: 0x21e4a8 in bang2 (error_return_trace)
    return error.PermissionDenied;
    ^
/home/ci/actions-runner/_work/zig-bootstrap/zig/docgen_tmp/error_return_trace.zig:30:5: 0x21e513 in hello (error_return_trace)
    try bang2();
    ^

        error.FileNotFound => try hello(),
                              ^
/home/ci/actions-runner/_work/zig-bootstrap/zig/docgen_tmp/error_return_trace.zig:7:9: 0x21e6b0 in foo (error_return_trace)

    try foo(12);
