[Sorry for the late reply, busy with school.]
The PC value suggests some botch relocation or something. Compare
the last several instructions in your gdb disassembly there with
what objdump -rd shows you on ld.so, and on the rtld.os file that
went into making it.
Alright, here is s the output from objdump on rtld.os, ld.so.1, and
the last few lines from the gdb disassembly. Not that this it makes
much sense to me...
