Hi, I am writing this because I just discovered a bad interaction between libgs, lcms2 and poppler.
Let me describe the situation first: * User is using Okular[1] to view documents * User opens a PS file. Okular loads a plugin that uses libgs to open the file * libgs calls cmsPluginTHR to set its own memory handler * User closes PS file. Okular unloads the plugin that uses libgs * User opens a PDF file. Okular loads a plugin that uses poppler to open the file * poppler uses lcms calls and since cmsPluginTHR was set by libgs but never reset when the libgs plugin was destroyed, lcms crashes The only solution I can think of from my side is never unloading the plugin that uses libgs, but I'd like not to get there. I looked at lcms code and doesn't seem to be a way for libgs to unload it's plugin (there seems to be a unloadAll, but that would not be a good idea either). Do you think it makes sense for lcms to provide such a functionality? Or anyone has a better idea?
