Package: cmake Version: 3.18.2-1 Severity: important Dear Maintainer,
* What led up to the situation? I tried to run cmake from bullseye/testing without arguments, it segfaulted immediately. Upgrading to latest from sid/unstable did not fix it. $ valgrind cmake ==6021== Memcheck, a memory error detector ==6021== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==6021== Using Valgrind-3.16.1 and LibVEX; rerun with -h for copyright info ==6021== Command: cmake ==6021== ==6021== Invalid read of size 1 ==6021== at 0x401C040: strcmp (strcmp.S:144) ==6021== by 0x4009F9B: check_match (dl-lookup.c:122) ==6021== by 0x400A3A3: do_lookup_x (dl-lookup.c:436) ==6021== by 0x400ACE0: _dl_lookup_symbol_x (dl-lookup.c:861) ==6021== by 0x400C843: elf_machine_rela (dl-machine.h:308) ==6021== by 0x400C843: elf_dynamic_do_Rela (do-rel.h:137) ==6021== by 0x400C843: _dl_relocate_object (dl-reloc.c:274) ==6021== by 0x40049A7: dl_main (rtld.c:2310) ==6021== by 0x401998E: _dl_sysdep_start (dl-sysdep.c:252) ==6021== by 0x4002033: _dl_start_final (rtld.c:485) ==6021== by 0x4002033: _dl_start (rtld.c:575) ==6021== by 0x4001097: ???
