FAT12 and FAT16 file systems don't have an +info_sector so pointer fs_info->info_sector remains assigned NULL from +fat_alloc(). When resizing a FAT file system create_resize_context() +was always dereferencing fs_info->info_sector to memory copy the +info_sector, hence it crashed for FAT12 and FAT16. + +Make create_resize_context() only copy the info_sector for FAT32 file +systems. + +Reported by Christian Hesse in +https://bugzilla.gnome.org/show_bug.cgi?id=735669 +--- +diff --git a/NEWS b/NEWS +index 297b0a5..da7db50 100644 +--- a/NEWS ++++ b/NEWS +@@ -2,6 +2,10 @@ GNU parted NEWS -*- outline -*- + + * Noteworthy changes in release ?.?
