Package: slirp Version: 1:1.0.17-9 Severity: important The last upload fixes slirp crashes directly on startup on amd64; It now just crashes when starting to use it....

Most likely all the usages of `#if SIZEOF_CHAR_P == 4` should be reviewed and fixed up to properly make slirp work on 64 bit systrms... -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.4.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages slirp depends on: ii libc6 2.29-9 ii libcrypt1 1:4.4.10-10 slirp recommends no packages. slirp suggests no packages. -- no debconf information
