Bug#720608: eclipse source editor screws up

[Dieter Teuchert]

Package: eclipse
Version: 3.8.0~rc4-1
Severity: important

Some days ago and yesterday once more i noticed text in a C source file
that wasn't meant to be there. First i did not trust myself enough to
believe there could be a bug in the eclipse source editor, but it
repeated. When i worked on a large source file yesterday, each of about
30 procedures in that file had a trace statement like

        g_debug("===>...some text label...\n");

on entry. For profiling i had to change all of them to

        g_debug("===>...some text label... %i usec\n",ElapsedUsec());

I did that by hand, selecting the '\n"' with the mouse and then Ctrl-v
to paste the ' %i usec\n",ElapsedUsec()' string as a replacement,
working through the file from top to bottom. After saving the file, i
started a "Build Project" and got two compile errors, because two of the
~30 '\n"' instances that were meant to be replaced/disappear showed up
at random locations in the source file ("extra"). I deleted them and
continued to work without any further problem.

So it's a random, rare error, yet rises some doubts on eclipse.

Although the machine is fast (AMD A8-5600K with 8 GB) there may be a
race condition between user editing and source checking and formatting
wizards. I am an experienced software developper and do that kind of
editing quickly. I have also been using the + and - block folding.
Eclipse is used with cdt, gcc and gdb, with two perspectives, all pretty
standard. The project is a GTK+ application using Cairo and ALSA, no
Java, no interprocess.
