Segmentation Fault on convert -resize

Hi,

I have somebug with convert. On Ubuntu linux 9.04. Installed imagemagick with all dependancy (apt-get build-dep imagemagick).

If I try to resize a picture I got a segmentation fault.

command: convert 1.jpg -resize 300x300 2.jpg

in syslog I have:
Sep 7 22:33:21 serveur kernel: [387054.357626] convert[3043]: segfault at 2c ip b78fa851 sp bfb5cb20 error 6 in libgomp.so.1.0.0[b78f5000+7000]



If I run it in DBG I get:

Code: Select all

(gdb) run 1.jpg -resize 300x300 2.jpg
Starting program: /usr/bin/convert 1.jpg -resize 300x300 2.jpg

Tested: convert a.jpg b.png and it work great. I don't know why resize failed....

Thanks

Looks like a bug in libgomp. The solution is to download / install the latest release of ImageMagick and see if that fixes the problem or rebuild your release of ImageMagick without OpenMP support (e.g. ./configure --disable-openmp).

I have instalelled from source with the option you tell me.

I now have an error when try to convert something:

error while loading shared libraries: libMagickCore.so.2: cannot open shared object file: No such file or directory

The file is there: /usr/local/lib/libMagickCore.so.2

Do it need to be somewhere else?

Thanks

Try 'ldconfig /usr/local/lib'. The command may be different on your host. Look for the command used to configure dynamic linker run-time bindings.
