compiler segfault

[dweiller]

Zig Version

0.11.0 and 0.12.0-dev.125+7ef1eb1c2

Steps to Reproduce and Observed Behavior

Clone https://github.com/dweiller/zubench (commit 83cbcff) and run zig build run. More minimally, run either of

zig test examples/fib.zig --test-runner src/bench_runner.zig --mod zubench::src/bench.zig --deps zubench
zig build-exe src/bench_runner.zig --mod @bench:zubench:examples/fib_build.zig --mod zubench::src/bench.zig --deps @bench,zubench

Expected Behavior

With zig build run there should be no error, with the zig test line above there should be a failing test (the failing one is removed with --test-filter fib); the build-exe should compile without issue.

I intend to update this issue after attempting to bisect the zig compiler to work out exactly when this segfault was introduced I have bisected the issue - details below.

Here's the output I get with a debug build of Zig 0.12.0-dev.125+7ef1eb1c2:

zig build-exe command

From what I can tell from the ZIR referenced in these outputs, both may be related to the issue reported in #16412, namely attempting to coerce .{} to an empty tuple type:

• zig test command: https://github.com/dweiller/zubench/blob/83cbcffc80b6157aff7dd2d1209bca4de2ead5b9/src/bench_runner.zig#L42
• zig build-exe command: https://github.com/dweiller/zubench/blob/83cbcffc80b6157aff7dd2d1209bca4de2ead5b9/examples/fib_build.zig#L21 (default initializer of args, an empty tuple type, is .{})

Bisecting seems to point to PR #15726 merged in commit 496320d. More specifically, that commit cannot run the zig test command above and commit 666ae24 (the commit before the PR was merged) can. The individual commits (other than the PR's final one) don't build by themselves so I couldn't narrow it down further. This seems to agree with @ianprime0509's assessment that it is do to with tuple coercion as the PR was reworking peer type resolution and tuple coercion. In fact replacing the empty anonymous tuple on line 42 of src/bench_runner.zig like this;

             allocator,
             bench_name,
             test_fn.func,
-            .{},
+            std.meta.ArgsTuple(fn () void){},
             options,
             max_samples,
             &progress,

makes the zig test compile successfully.

FYI, this is working for me as of 0.12.0-dev.722+412d863ba (see also #17380 which adds a behavior test for this case).
