Summary0001630: Illegal Memory Access when running dot.exe with single nodes
Description






When I run
<CD>
    C:\Programme\Graphviz2.22\bin>dot.exe -Tgif -O C:\Temp\input_with_single_nodes.dot
</CD>
with the attached input file, the program terminates with the message
<CD>
    Die Anweisung in "0x68dd2dd2" verweist auf Speicher in "0x68e1c570". Der Vorgang "written" konnte nicht auf dem Speicher durchgeführt werden.
</CD>
which means in English
<CD>
    The instruction at "0x68dd2dd2" referenced memory at "0x68e1c570". The memory could not be written.
</CD>



After shifting all the 'single node' lines of the form
    "a_name,a_version_number";
(i.e. without an '->' arrow) at the end of the file, just before the closing '}', the error message changes to (in English)
    The instruction at "0x68dc1c68" referenced memory at "0x00000004". The memory could not be read.
When doing the same on another computer with the same OS / OS version, the error messages is
<CD>
    dot.exe hat ein Problem festgestellt und muss beendet werden
which means in English something like
    dot.exe has an error detected and has to be closed.
In this case the error signature is:
    AppName: dot.exe
    AppVer: 0.0.0.0
    ModName: libcairo-2.dll
    ModVer: 0.0.0.0
    Offset: 00012dd2
</CD>
The technical error report informations are quite long and may not be copied from the Window, in which they are displayed, so I send them on request only. Except for one file, which is stated to be a part of the error report, which I attach here: 5512_appcompat.txt



Additional Information


- When deleting the a.m. single node lines dot.exe runs fine. But I do need the single node lines. Otherwise I wouldn't be able to see nodes without connections as well.

- In addition to the error I see a warning
    (dot.exe:5116): Pango-WARNING **: couldn't load font "Times Roman Not-Rotated 14", falling back to "Sans Not-Rotated 14", expect ugly output.
  which seem *not* to be related to the reported error

TagsNo tags attached.

testing using 2.33.20130907 on XPSP3 (clean system)
results in this application failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem.

Reinstalling does not fix the problem.
