Hi, The for loop in libgcore/gcore_coredump.c:fill_thread_core_info() does a notesize(struct memelfnote *) where memelfnote->name points to the name of the corresponding arm_regset member (except REGSET_GPR). But notesize calls strlen on those strings and arm_regsets[REGSET_VFP]->name == 0x0 making it segfault. Regards, Per
