...configuring "--disable-hardening" removes the "-fstack-protector-strong" compiler option, which resolves this issue. Issue 3) dovecot/doveconf segfaults on startup It crashes here while processing dovecot.conf, as does "doveconf" (settings-parser.c:1519 in setting_copy()) *dest_size = *src_size; It appears *src_size is not an 8-byte address aligned (0x5597c). It inherits this value from the calling routine as the sum of "set" (8-byte aligned) + "def->offset"=20 => misaligned address. (settings-parser.c:1597 in settings_dup_...
