Could you give a bit more information on how you build and run eu-objdump?

I am unable to replicate your results with the given poc.
It simply works as intended:

$ eu-objdump -d ./b
./b: elf64-elf_x86_64

Disassembly of section .fini:

aaaaaaaa:    48 83 ec 08              sub     $0x8,%rsp
aaaaaaae:    48 83 c4 08              add     $0x8,%rsp
aaaaaab2:    c3                       retq

Also it is somewhat surprising it crashes for you inside default_syscall_abi ()
because that doesn't seem to be called. Which indicates the error is somewhere
else.
