Zig Version

0.10.0-dev.3659+e5e6eb983

Steps to Reproduce

This is a weird issue and I'm not entirely sure how to trigger it. Over time, tests begin to fail building more frequently. Here's an example on a brand new project:

// build.zig
const std = @import("std");

pub fn build(b: *std.build.Builder) void {
    const a_tests = b.addTest("src/a.zig");
    const b_tests = b.addTest("src/b.zig");
    const c_tests = b.addTest("src/c.zig");

    const test_step = b.step("test", "Run unit tests");
    test_step.dependOn(&a_tests.step);
    test_step.dependOn(&b_tests.step);
    test_step.dependOn(&c_tests.step);
}
// a.zig, b.zig, c.zig all contain the following
test {}

I'm not sure if this problem also exists on stage1 because self-hosted recompiles things every zig build test, but stage1 just runs the cached test binaries.

Expected Behavior

There shouldn't be any build failures.

Actual Behavior

Command line output:

d:\Scratch\testfailure>zig init-exe
info: Created build.zig
info: Created src\main.zig
info: Next, try `zig build --help` or `zig build run`

Closing this as I can no longer reproduce the problem as of 527055a and having switched from MSVC to zig-bootstrap.
