> The bug is in the fat module's [http://cgit.haiku-os.org/haiku/tree/src
/add-ons/kernel/file_systems/fat/dir.c?id=hrev45732#n92 _next_dirent_()].
At a quick glance the `filename` variable that is passed points to a
buffer that hasn't been initialized yet -- that happens later in the
function when an entry has been found -- so it doesn't make any sense to
print it. There's a `dprintf()` a few lines earlier with the same issue.
What may make some sense to print are the information passed to the
`DPRINTF()` in line 81.
And it looks like there might be another case at the end of
get_next_dirent() per CID 603015 that someone should probably clean up as
well.
