This is explained in the comments in the relevant source file. Note that it is hidden and not exported from libc. /* Because some objects in ld.so and libc.so are built with -fexceptions, we end up with references to this personality routine. However, these libraries are not linked against libgcc_eh.a, so we need a dummy definition. This routine will never actually be called. */ -- Joseph S.
