The strtab errors come from the linking hence from binutils. The only
causes I can imagine is whether there is a lib used that has been
compiled with an old version of the binutils, or a component was
compiled requering an old version of the toolchain and hence bringing in
an old version of the binutils.

Concerning the core dumps, there is another thing to look at:
_FORTIFY_SOURCE. There are checks about the use of strings functions
that can cause an abort even if the actual use is probably, with
a classic C implementation, safe---I hit it with a strcpy() that was
removing a prefix simply shifting bytes left in a buffer; it didn't
cause any harm before 9.* and now aborts because src and dst overlap.
