Although I'm not familiar with every Unix implementation, the ones I've 
seen don't include the text segment in a core file.  The exception to 
this rule is if you've specially linked your load module to place all of 
the program text in the data segment (i.e.  non-split I+D).  This is 
usually only done when you've a need to modify the text while the 
program is executing via a debugger.  But commercial products aren't 
usually shipped as non-split I+D load modules.  

Core files also don't usually include shared libraries, shared memory 
segments, and/or memory mapped files.
