Did you log the file name of the Elf_file? Where is it located? What's
the output of "objdump -p elf_file"?
Two files are loaded:
- name=ld.lib.so
- name=binary
I'm guessing, that binary is expanded to the name of the binary to run,
which is wamedge.
The output is as follows:
```
% objdump -p var/bin/x86_64/wasmedge
var/bin/x86_64/wasmedge: file format elf64-x86-64
