Symptoms
On Solaris 10 with kernel patch 147147-26 (SPARC) or 147148-26 (x86) installed, and on Solaris 11.1 or newer, the ldd -d command reports warnings on binaries linked with the incremental linker.

Changes
The problem shows up only with ldd from Solaris 10 1/13 (Update 11) resp. ldd from Solaris 11.1, or newer.
The problem shows up only for binaries linked with the incremental linker.
The incremental linker created objects with "holes" for various sections.
These holes could then be filled in with the material from future incremental links.
For that purpose, it uses so-called move sections.
To identify binaries which have been linked with the incremental linker, mcs can be used:
