------- Comment #4 from carlos at systemhalted dot org 2010-01-31 16:54 ------- That is correct, all glibc targets must provide the current version if libgcc_s.so. The NPTL implementation of pthread_cancel_init will dlopen that current version of libgcc_s.so and use the unwinder implementation from that library.
