Add '-g -ggdb' to your build options in order to enable debugging and 
then use GDB to debug the issue.  Make sure that you have installed 
the 'graphicsmagick-dbg' Ubuntu package so that you can see what is 
going on inside GraphicsMagick.

Use

   ulimit -c unlimited

in your shell configuration in order to allow core dump files to be 
created.

Many people find Kdbg ('kdgb' Ubtuntu package) to provide a 
user-friendly way to do debugging.
