Which one of these calls to find_plt_ent returned NULL? None of them should, so it indicates we have a bug somewhere else. Please open a bug report at http://sourceware.org/bugzilla/enter_bug.cgi?product=binutils preferably with a self-contained testcase (since this is a ld bug, we want the inputs to ld, ie. object files, libraries, and any ld scripts), or failing that, more information on how to reproduce the problem including such details as the exact version of your compiler and libraries. > N.B.: I still have error messages such as "Error: Unrecognized opcode: > `slwi'", but at least ld does no longer segfault.
