Crash when MagickNewImage params are incorrect

[mkoppanen]

Code: Select all

#include <stdlib.h>
#include <wand/MagickWand.h>


int main() {

        MagickWand *wand;
        PixelWand *color;

        MagickWandGenesis();

        wand = NewMagickWand();
        color = NewPixelWand();


        PixelSetColor(color, "white");


        MagickNewImage(wand, 0, 75, color);


        MagickWandTerminus();
        return 0;
}

Here is a backtrace:

Code: Select all

Tested with 6.4.5, might be fixed in current.

Thanks!
