Prior to starting to look at JUCE to see if it will meet my needs, I had been using a very simple host made by Herman Seib (http://www.hermannseib.com/english/vsthost.htm) to do some testing of vsts that I made.
Recently, I made a very vanilla vst with JUCE; in fact, it is just a blank gui editor. Upon closing the vst, Mr. Seib's host told me there is a memory allocation error. I did not receive a similar message in Reaper, Logic, or the demo for Bitwig.
The vst was set up the same way as the Redwood demo (http://www.redwoodaudio.net/Tutorials/juce_for_vst_development__intro.html), though it includes no Timer or code for the stereo width control they made.
Having said this, I am no expert programmer, so I am wondering if anyone has come across this before and how they tracked down the problem.
Thank you all.
