Distributions would have to triple the number of CDs shipped. Most users don't know how to run a debugger. This means that there is no debug information available until a developer tries to duplicate the problem report. With or without cross-jumping, when the developer gets a report from a user that "the program died with an abort", he or she has to debug from scratch, only to find out in many cases that it's a known bug, already fixed in CVS for the next release, information that would have been revealed immediately by the output of fancy_abort.
I agree. I find this a vert strong argument.
