The tests pass both in CI and on my person M1 Mac Mini. Could you share the following:

• The macOS version used
• The LLVM version used

In addition, could you run the following and share the output:

# In a git clone of the main branch:
cd std
cargo run -- build --threads=1 --release --no-codegen --escapes=main fixtures/escape/call_with_non_heap_values.inko

[winterqt]

• The macOS version used

26.5.2 (25F84)

• The LLVM version used

18.1.8

I can try with a newer version, I just thought 18 was ~suggested based on the llvm-sys version. (Though based on a ~recent Inko release's changelog, this doesn't seem to be true.)

cargo run -- build --threads=1 --release --no-codegen --escapes=main fixtures/escape/call_with_non_heap_values.inko

This produced no output.

[yorickpeterse]

@winterqt LLVM 18 indeed should be fine. If you have lldb installed, can you run the following with lldb and share its output:

# from the std directory:
lldb -- ../target/debug/inko build --threads=1 --release --no-codegen --escapes=main fixtures/escape/call_with_non_heap_values.inko

I suspect the compiler is crashing but IIRC macOS hides the usual "this program triggered a SIGSEGV" errors unless you run the program under lldb.

[winterqt]

Nope, it's definitely not SIGSEGVing:

Process 29987 launched: '/Users/winter/src/inko/target/debug/inko' (arm64)
Process 29987 exited with status = 0 (0x00000000)

[yorickpeterse]

@winterqt Unfortunately without any output or errors I'm not sure what would cause this, you'd have to start playing around with lldb and/or printf debugging to try and figure out where/why the compiler just aborts.
