Package: e2fsprogs
Version: 1.39-1
Severity: important
Hi, e2fsck segfaults when checking an ext3 fs.
I suspect the corruption was due to my writing to the ext3 from Windows XP
using the driver from http://www.fs-driver.org/ which does not appear to
support -O dir_index (but happily tries to write stuff anyway).
e2fsck rebuilt with -g:

Fix potential e2fsck -n crash
Don't core dump if there is a corrupt htree interior node. If the block
number is larger than the number of blocks in the directory, don't write
past the end of malloc'ed memory.
