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
