Oh... I changed code adding a core if "invalid string offset", removed it give
$ hppa64-hp-hpux11.00-ld -shared ct.o ctutil.o
hppa64-hp-hpux11.00-ld: ctutil.o: invalid string offset 1734672384 >= 27 for
section `.strtab'
So it does not core... however I'm still thinking about symoffset, I added that
line and after core bt gave

(I don't know if this can help you). symoffset came from allocate dynamic
section however why an output symbol should change how the symbols from source
file is read?? Well.. I have to say that I don't know so much linker internals
and elf structure but it seems strange. Note also that check for symbol boundary
is done only on second read (see bfd_elf_get_elf_syms, just after pos
computation)
