But I have really no idea why. The jpeg_finish_decompress is from the jpeg libary or jpeg-mmx for some strange reason the crash happens with each lib. :-/ Allocating more memory did not solve the problem on my machine.
But when the image has a size of at least 200x160 ist does not crash. That makes it rather strange. > jpeg-mmx-0.1.4.tar.gz > libmovtar-0.1.3.tar.gz > mjpegtools-1.6.1.92.tar.gz > quicktime4linux-1.4-patched-2.tar.gz > > on a Debian Sarge (testing) system with gcc-3.3.2 Tested it on a Suse 9.0 > I hope this report will help to improve future versions of this great software Thanks auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This SF.net email is sponsored by: Perforce Software.
