compiled hello.jl segfault

[XilinJia]

This relates to discussion in the forum: https://discourse.julialang.org/t/aot-compiled-hello-jl-core-dump/19318/5

First copy hello.jl into a tmp folder. Then

$ julia

Not sure what is going on, I then copied hello.so from builddir into my JULIA_BINDIR: /home/user/Software/julia-1.0.3/bin/, then:

builddir]$ ./hello

signal (11): Segmentation fault
in expression starting at no file:0
unknown function (ip: 0xffffffffffffffff)
main at ./hello (unknown line)
__libc_start_main at /usr/lib/libc.so.6 (unknown line)
_start at ./hello (unknown line)
Allocations: 3278 (Pool: 3266; Big: 12); GC: 0
Segmentation fault (core dumped)

But if I copy all files in builddir into my JULIA_BINDIR, then it works.

How can I not copy all files into JULIA_BINDIR?

How about trying build_executable("hello.jl","hello") instead of build_executable("hello.jl") ?
I always do so and it works fine.
