Hi, I'm re-assigning this bug to libqalculate-dev based on the high similarity with #1077798 .
Moreover, diffoscope-ing between libqalculate-dev_5.3.0-1_i386.deb and libqalculate-dev_5.4.0.1-1_i386.deb : │ │ ├── ./usr/lib/i386-linux-gnu/pkgconfig/libqalculate.pc │ │ │ @@ -1,12 +1,12 @@ │ │ │ prefix=/usr │ │ │ exec_prefix=${prefix} │ │ │ libdir=${prefix}/lib/i386-linux-gnu │ │ │ includedir=${prefix}/include │ │ │ │ │ │ Name: libqalculate │ │ │ Description: libqalculate │ │ │ -Version: 5.3.0 │ │ │ +Version: 5.4.0 │ │ │ Libs.private: -lcurl -licuuc -licudata -lgmp -lmpfr -lpthread │ │ │ Requires.private: libxml-2.0 >= 2.3.8 │ │ │ Libs: -L${libdir} -lqalculate │ │ │ -Cflags: -I/usr/include/i386-linux-gnu -I/usr/include/p11-kit-1 -I${includedir} │ │ │ +Cflags: -I/usr/include/i386-linux-gnu -isystem /usr/include/mit-krb5 -I/usr/include/p11-kit-1 -I${includedir} that's IMO an additional clue of this issue residing in libqalculate. Please let me know otherwise. Kind regards Marco
