module HelloWorld

Base.@ccallable function main()::Cint
    println(Core.stdout, "Hello world")
    return 0

1.13.0-DEV.325, Windows 11, Powershell:

julia juliac.jl --output-exe hello --trim --experimental hello.jl

Compiles to a 12.7 MB binary, but gives an error when run:

Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks. Exception: EXCEPTION_ACCESS_VIOLATION at 0x7ff959ffcd21 -- Hello world

After compiling without --trim --experimental the resulting exe works fine.

On 1.12-beta1, compiles to 1.8 MB, gives the following exception:

This is also occurring with the non-trimmed version, without --trim --experimental in the compile command

[johroj]

I can reproduce this this error.

Steps I took:

• Download 1.12-beta1 windows installer
• Add 1.12-beta1/bin to PATH
• Replace cc with gcc in juliac.jl to make it compile at all.
• Copy hello.jl from the source code to my local drive
• Run juliac with and without the --experimental --trim flags.

Should be fixed by #58141

(and the correct gcc to use will be provided by #57481 - the choice is a bit subtle, since you need to use a compatible ABI)
