Hmmm, this looks like you have either compiled GNUstep with -DDEBUG  
or you have set the environment variable CRASH_ON_ABORT. In both  
cases, the signal handler installed by gdnc will call the abort  
function. Unfortunately, the handler is installed for SIGABRT, too,  
which causes the infinite recursion you are seeing. Probably, the  
best fix is to not install the signal handler for SIGABRT. The  
following patch should fix that.
