[Bug 1611133] [NEW] dpkg truncates lines in 'status' file which begin with two spaces.

[Dragan S.]

Public bug reported:

On Ubuntu 12.04.5 LTS command dpkg version 1.16.1.2ubuntu7.7 seems to
experience issues when updating packages.

In one instance the status file seems to have over a thousand lines that
have been truncated. It only seems to truncate package comments that are
indented with two spaces. No indent or single space indent lines are all
fine but lines that have a double space get truncated. They are not gone
in the file they are just replaced by a line that has two spaces and a
new line.


Programmatically I would describe the problem as in perhaps a failure in reading the comment from the source and writing an empty string into the target:

Comment = read_comment(next_line);

fprintf(Status, "  %s\n", Comment);

So if there was an error in read_comment and function returned an empty
string "", this would explain why some lines were getting truncated.
