Binaries were build for amd64 architecture (the issue):

Just for reference, architecture i386 is expected:

debian@atom$ file /bin/bash
/bin/bash: ELF 32-bit LSB pie executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, BuildID[sha1]=2d1c62b4bd89f14c30f1ea1281fbbb05bd785fb0, for GNU/Linux 3.2.0, stripped

This is correct, i386 is identical binary as amd64 in our case. We did not have any previous complains about this and most were running fine with it. Agreed that we should adjust travis and create better pipeline for it.

[PSLLSP]

I assume it is possible to run this "i386" code on 64-bit system but it is impossible to run it on 32-bit OS. I test it on 32-bit system and I see the issue.
