Package: libdng1 Version: 0.2.1-1 Severity: normal X-Debbugs-Cc: andrej.skvort...@gmail.com
Dear Maintainer, I've worked on Megapixels, that uses libdng. The application worked correctly until libtiff6 was upgraded from 4.5.1+git230720-5 to 4.7.0-3. After upgrade Megapixels crashes, when photo is taken with following backtrace: ``` Thread 8 "megapixels-pr" received signal SIGSEGV, Segmentation fault.

After I've built libdng1 against newer libtiff6 (4.7.0) crash disappeared and megapixels works as expected. It looks like libdng1 needs rebuilt and reupload. -- System Information: Debian Release: trixie/sid APT prefers testing-debug APT policy: (500, 'testing-debug'), (500, 'testing') Architecture: arm64 (aarch64) Kernel: Linux 6.12-sunxi64 (SMP w/4 CPU threads) Kernel taint flags: TAINT_CRAP Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libdng1 depends on: ii libc6 2.40-6 ii libtiff6 4.7.0-3 libdng1 recommends no packages. libdng1 suggests no packages. -- no debconf information
