If you interrupt doxygen while it's creating the PNG call graphs, then you get the PNG output to the console in binary form.

Not only is it a bunch of gibberish, it sometimes messes with the console settings for fonts and colours and such. Additionally, since they're not immediate children of the shell, you can't interrupt them with another Ctrl+C.

It seems like the main doxygen process closes, but doesn't cancel any of the graph processes, which spew to console, since their parent is gone.

Steps to Reproduce:

  1. Start a Doxyfile with call graphs enabled.
  2. Run doxygen.
  3. Hit Ctrl+C when it gets to the graph creation step.

Actual results:
The binary PNG data is printed on the console.

Expected results:
doxygen should exit without any extraneous output.

I haven't been able to reproduce this completely, but I have improved SIGINT handling, so that would hopefully prevent this behaviour.
