It's because we zero _ns_debug now, and the code in elf/dl-debug.c does not cope with that. I've already posted a patch series that removes _ns_debug again, but just clearing libc_map instead of the full memset is probably the more conservat= ive approach here. --=20 You are receiving this mail because: You are on the CC list for the bug.=
