Non-deterministic build failures with -debug flag #3028

Closed iansimonson closed 10 months ago

iansimonson commented 10 months ago

Context

I have been running into non-deterministic build failures on MacOS when compiling with the -debug flag. This seems to have started when I set the context.allocator in a test case but that is probably unrelated.

It also occasionally hangs

Odin report:

        Odin: dev-2023-12:67d02043f
        OS:   macOS Monterey 12.5 (build: 21G83, kernel: 21.6.0)
        CPU:  Intel(R) Core(TM) i5-7267U CPU @ 3.10GHz
        RAM:  8192 MiB

Expected Behavior

The compiler should build successfully with debug information

Current Behavior

There are non-deterministic failures that are occurring, and different ones each time. The ones I've seen are:

MDNode context does not match Module context!
!4393 = !DIDerivedType(tag: DW_TAG_typedeffish: Job 1, 'odin build . -debug' terminated by signal SIGSEGV (Address boundary error)
fish: Job 1, 'odin build . -debug' terminated by signal SIGSEGV (Address boundary error)
invalid base type
!4355 = !DIDerivedType(tag: DW_TAG_member, name: "less", file: !4348, baseType: !"fish: Job 1, 'odin build . -debug' terminated by signal SIGSEGV (Address boundary error)

also in some instances the compiler just hangs (deadlocked?)

Failure Information (for bugs)

I have not seen this on other files, so for the record this is the file producing the issue: (txt because github doesn't allow uploading .odin files) day17.txt

Steps to Reproduce

odin build . -debug or odin test . -debug both cause the issue to occur

Duplicate of https://github.com/odin-lang/Odin/issues/2945 I assume

Looks like it, I'll copy these backtraces over to that issue and close this one
