Um, I've never seen this kind of error so far. From the result of fsck, it seems that the inode of shared.h was lost. So, currently, there is no way to recover that inode and its data simply. It may need scan the whole partition to find the stale inode block. Two questions. - Have you experienced any sudden power-off before? - Can I test with the repository having the shared.h that you used? (I'd like to do a simple test storing that repository.)
