"Illegal instruction" when running hushd #310

Describe the issue

After installing the latest hushd 3.9.4 debian package, running hushd produces the error message of Illegal instruction and it does not start.

Can you reliably reproduce the issue?

If so, please list the steps to reproduce below:

Install hushd 3.9.4 with sudo dpkg -i hush-3.9.4-amd64.deb.
Run hushd.
Only see Illegal instruction as output.

Expected behaviour

hushd will start running hushd

Actual behaviour + errors

Explained above

The version of Hush you were using:

Run hushd --version to find out

it's 3.9.4, but --version also produces Illegal instruction and does not work.

Machine specs:

OS name + version: Ubuntu 20.04
CPU: Intel(R) Xeon(R) E5-2680 v2 (3) @ 2.799998 GHz
RAM: 4.31 GB
Disk size: 94 GB
Disk Type (HD/SDD): Unsure
Linux kernel version (uname -a): Linux HOSTNAME 5.4.0-153-generic #170-Ubuntu SMP Fri Jun 16 13:43:31 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
Compiler version (gcc --version): gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0

Any extra information that might be useful in the debugging process.

For the broken 3.9.4 hushd, I find the following

$ file /usr/bin/hushd
/usr/bin/hushd: ELF 64-bit LSB shared object, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=0a885319ec58f8bb4c78d7180a0806ce25a91b68, for GNU/Linux 3.2.0, stripped

Then I compare this to the working 3.9.3 hushd and find the following:

$ file /usr/bin/hushd
/usr/bin/hushd: ELF 64-bit LSB shared object, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=7290b99ac4a3aeb0786a35e88b6b961a785b5d9a, stripped

Yes, I am seeing this too. I tested the binaries since the Debian package uses those. strace hushd --version ends with

--- SIGILL {si_signo=SIGILL, si_code=ILL_ILLOPN, si_addr=0x55facaa89198} ---
+++ killed by SIGILL (core dumped) +++
Illegal instruction (core dumped)

I have tested the hushd 3.9.4 debian package on the following:

OS	CPU Type	Result	Model name in /proc/cpuinfo
Ubuntu 20.04	AMD	Illegal instruction (core dumped)	Common KVM processor, but "AMD Ryzen 5 PRO 2400GE w/ Radeon Vega Graphics" on the bare metal
Ubuntu 20.04	Intel	Illegal instruction, which is documented in original issue	Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
Debian 11	AMD	Illegal instruction	Common KVM processor, but "AMD Ryzen 5 PRO 2400GE w/ Radeon Vega Graphics" on the bare metal
Arch	AMD	Illegal instruction (core dumped)	AMD Ryzen 7 2700 Eight-Core Processor

@jahway603 can we close this issue? I think we have working bins now

Yes, this issue has been resolved & can be closed.
