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
