I am not so sure. Heaptrc outputs to stdout. If the application is compiled -WG the 
RTL redirects the output to message windows. I would recommend to let heatprc write 
to file. See http://www.freepascal.org/docs-html/rtl/heaptrc/environment.html and/or 
http://www.freepascal.org/docs-html/rtl/heaptrc/setheaptraceoutput.html

I disagree. Any GUI application with heaptrace has the same issue.

OTOH, if the output is redirected to file, Lazarus has a nice view: leakview, a ide 
plug-in you can find in lazarus\components\leakview
