Package: dosfstools
Version: 3.0.26-4
Followup-For: Bug #764992
This bug seems to be caused by uninitialised dir entry fields for the
root directory.
Valgrind shows 2 errors about "conditional jump or move depends on
uninitialised value"
Initialising the dir entry structure when constructing the root
directory fixes
the issue.
The patch check.c.patch fixes this issue and valgrind no longer shows
errors about uninitialised values.
