Zig bootstrap crashes build on ReleaseSafe

[kassane]

Zig Version

0.12.0-dev.3518+d2be725e4

Steps to Reproduce and Observed Behavior

Using latest zig-master src on bootstrap: d2be725

• build zig (cmake + wasm) [RelSafe]: OK
• build LLVM using zig: OK
• build zig using zig(cmake+wasm)[RelSafe]: Fail

Expected Behavior

Successful build. ReleaseFast works.

• build zig (cmake + wasm)[RelFast]: Ok
• build llvm using zig[RelFast]: Ok
• build zig[RelSafe] using zig[RelFast]: Ok

[Vexu]

Did you update the bootstrap wasm blob as well?

[kassane]

Did you update the bootstrap wasm blob as well?

This? e5ba70b (yes)

[kassane]

I don't know if it's clear enough.

• Zig(wasm) build Zig(host) ReleaseSafe: OK
• Zig(host)[ReleaseSafe] build Zig(triple-targets) ReleaseSafe: Fail

But,

• Zig(host)[ReleaseFast] build Zig(triple-targets) as ReleaseSafe: Ok

[Vexu]

Can you try clearing the global cache?

[kassane]

Can you try clearing the global cache?

clean (global + local) cache, get same error!

[nm-remarkable]

There were some breaking changes to @fieldParentPtr. Ref: #19470
