How can I debug program linking specific version of shared library?

helloworld.c:

int main(){}

[1] 9845 illegal hardware instruction (core dumped) LD_PRELOAD=./libc.so.6 ./helloworld

This preload libc is an old version of glibc

Can I debug helloworld linking it on my system?

Or is there a fast way to deploy a virtual machine with the specific version of shared libraries?
