Fail on test suite and etshell

[huxiaobang]

I've tried several versions of x86_64 ubuntus from 20.04 to 18.04.1 which was mentioned in the original paper, but all failed on the jumptable-libc.sh test with

<<< 0x00044820 [vfprintf] has 30 entries
>>> 0x00044820 [vfprintf] has 1 entries

In etshell, the program always crashes with segfault when trying to archive hello.ega as mentioned in the tutorial, with logs

-- checking relocation for module module-(executable)
relocation at 200fd8 with addend 0 NOT resolved! (no link)
[...] //during parsing

Trying to assign serialization ID to null chunk, skipping
Trying to assign serialization ID to null chunk, skipping
Trying to assign serialization ID to null chunk, skipping
Segmentation fault (core dumped)

Is there a way to solve the problem?
BTW egalito.org website seems to be down, could you kindly fix it?
