It's a bit difficult to be sure what's gone wrong with this level of detail.
Ideally, this output ought to include line numbers as well, so we
could tell exactly where the problem is occurring.
But there are only a few mentions of 'strlen' in hr_swinst.c
And given that this is a Solaris box, the I suspect that problem
lies with the handling of pkgparam(..., "VERSION")
I'm attaching a patch that might possibly help.
Note that you'll need to apply this to a source distribution,
and recompile the software.
