I'm experimenting with GHC (5.00.1) on RedHat Linux 7.1, it's foreign function interface (using .hsc files) and the SDL graphics library (v1.2). The curious thing is that the following code: main = sdlInit [sdlVideo[ sdlQuit can be loaded into GHCi and executed as many times as I like, however, if I then carry on and edit the module containing main, and then perform a reload (:r), I sometimes get an "EVACUATED object entered!" message and GHC crashes on me: TestGraphics> :r Compiling TestGraphics ( TestGraphics.hs, interpreted ) Ok, modules loaded: TestGraphics, SDL, Rectangle, SDLEvents, SDLKeySyms, ForeignUtil. TestGraphics> main EVACUATED object entered! make: *** [interactive] Error 1 bash$ What does this error mean, and why is it only triggered when I perform a reload in GHCi? Sometimes the reload works fine, and other times I get a segmentation fault. Thanks John
