I've never used electric fence, and I couldn't find any documentation online 
in the 60 seconds that I took to look, but...

Are you sure that you're supposed to use LD_PRELOAD and gdb with Electric 
Fence.  Sometimes, memory debugging tools let you run the program, and then 
they dump a report at the end...no debugger needed.

It's possible here that the LD_PRELOAD is forcing gdb to use Electric Fence.  
Perhaps that's your problem?  You can probably enable LD_DEBUG or LD_VERBOSE 
(man ld.so) to determine what's going on with the libraries.

But then you don't get what you want from Electric Fence.
