[crash] image display problem on 24bpp

XEmacs inline image display cause crash on 24bpp X. 1. $ xemacs -vanilla 2. C-x C-f imagefile After broken (monochrome, vertical lined) image or nothing is displayed, XEmacs crashes. PNG, JPEG, TIFF, GIF formated image has this problem, and XPM does't. This is 100% reproductive in my one environment, but not occur in other environment. I heard some X server (for example, XFree86 SVGA I am using in the environment) handle 24bpp images without padding to 32bit and this cause image display problem in some software which handle image directly. I think XEmacs is one of them. uname -a: Linux agenv4 2.0.36 #1 Thu Nov 19 12:33:18 JST 1998 i586 unknown ./configure '--compiler=egcc' '--with-mule' '--with-xim=no' XEmacs 21.0-b61 "Poitou61" configured for `i586-pc-linux'.
