@jperkin hm this almost strikes a bell, as if something like this happened a couple of years ago
@jperkin For Solaris, it appears it works okay with binaries linked on Solaris 11.4, but not on earlier Solaris versions, since in 11.4 we set the size correctly in the PT_DYNAMIC phdr, where earlier releases (and current illumos) does not, as @richlowe is currently fixing in https://www.illumos.org/issues/15361 .
