It worked, fine.

This way, gdb as well as the prgram to debug both use libefence. Since 
efence can slow don execution and increas memory usage dramatically, 
you might prefer to only let the program to debug use efence.

The easy way is to not run the target in the debugger but let is dump 
core and use the debugger to do a post mortem core analysis. The other 
option is to set the environment variable inside gdb.

It could have been usefull to have executed 'up', to see the call to 
strcat() and then to print its arguments.
