Package: mtools Version: 4.0.23-1 Running e.g. mdir -i $SOMEFILE@@$LARGEOFFSET fails when the offset exceeds around 2GB. The error message is:
| seek: Invalid argument | init :: could not read boot sector | Cannot initialize '::' Using strace one can see that mtools tries to seek the image to a negative offset that results from treating the desired offset as a signed 32bit number. The problem was only observed on armhf and could not be reproduced on amd64. Most likely, it can be fixed by adding -D_FILE_OFFSET_BITS=64 to the CFLAGS. Helmut
