emacs adds trailing whitespace in comments when copying from terminal

Example of .c file to test the bug
Description of problem:
When I select text from a source file with emacs-nox or emacs -nw if I select commented code the text selected includes non-existant trailing whitespace. This happens with various types of source code, I've tested with .c and lisp. Also, I tested with no .emacs file so this basically happens on a clean emacs installation.
Version-Release number of selected component (if applicable):
emacs 24.3 fc19 x86_64
Steps to Reproduce:
1. start emacs -nw
2. open a .c file with comments
3. select lines that include comments, those lines are selected until the end of line. Lines without comment will only be selected until the last character (i.e. no trailing whitespace).
Lines with comments should only be copied as any other line, until the last character.
I think this has something to do with the way emacs does syntax highlighting, because if you rename the .c file to .c_old this bug doesn't appear.
I've found out this is happening when semantic mode is turned on.
I meant, that this also happens with semantic mode on all lines, not just comments. Sorry for the confusing comment.
This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 19 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
