It could occur when the user has multiple versions of a library
installed for whatever reason, and Julia works one version (the
one that it was “build” and tested with), but fails/segfaults
with the other(s) due to an ABI incompatibility.

This may happen during the upcoming transition of libsparsesuite
for julia 0.4.0 from libcholmod2.1.2 and libumfpack5.6.2 to
libcholmod3.0.6 and libumfpack5.7.1.

Yes, that is exactly what I am exploring right now.

I compile a dummy executable in override_dh_shlibdeps and pass it
using `dh_shlibdeps -- -e dummy', which already generates Depends.

I will upload a prototype to a personal branch for your review. I will
see whether it is not too much work after all to patch julia to use
the sonames, which would avoid the symlink mess.
