"-debug" slows down GIF output

Usually, "-debug" has no big significance on the speed of an ImageMagick command (especially when there are no debug messages to print). Example:
Both commands are very quick. 
But now with GIF:
The second command is veery slow on my system. Seems odd!? If I increase the GIF size furthermore, I even have to kill the process sometimes when using a "-debug" option.
It seems to be.. delayed mostly at a RelinquishMagicResource method at the end (or is it the one that follows?):...
