Hi, Dear Debian octave devel team
Happy New Year!
I'm a Octave user. I've aptitude installed the octave-3.2.4 (Source
Package: octave3.2 3.2.4-12) [Wheezy/testing] on my 64-bit PC (AMD X955 4
cores) and most of octave functions is OK.
But when I call the imread and imshow function to load a JPEG picture, I
encountered a segmentation fault problem like following :
% -------------------- imread seg fault ----------------------
octave-3.2.4:1> imread('/home/mywork/temp/pic/003.jpg')
octave-3.2.4: magick/pixel_cache.c：2765：ModifyCache: Assertion
"image->cache != (Cache) ((void *)0)” failed
panic: Aborted -- stopping myself...
% -------------------- imread seg fault ----------------------
% -------------------- imshow seg fault ----------------------
octave-3.2.4:1> imshow('/home/liuxiangyu/temp/pic/003.jpg')
panic: Segmentation fault -- stopping myself...
Segmentation fault
% -------------------- imshow seg fault ----------------------
I don't know where I can find the reason, so I do some compiling
experiments.
I tried to compile the lastest octave-3.4.3 manually. I downloaded the
source tar ball from www.octave.org and aptitude install some dep-package
such as libreadline-dev, libncurses5-dev, libgraphicsmagick++1-dev,
libfltk1.1-dev and so on. Compiling is successfull , but make check also
encountered the seg-fault when run script/imread.
I saw some bug-mail-list on google talking about GraphicsMagick and
bit-wide. I compiled the newest GraphicsMagick-1.3.13 manually with
configure parameter --with-quantum-depth=16, and compiled octave-3.4.3
manually (config octave to link to GraphicsMagick-1.3.13 in
/usr/local/lib), but, I also encountered the seg-fault when run
script/imread. And I can't debug the octave or imread (cause I don't know
how to use gdb or some tools else) to find the reason.
So I send this mail to you to look for help, any advice or comment from you
would be most welcome.
Following are some informations about my PC, gcc, CPU.
