That's a bit odd, it shouldn't have all zeros as parameters -- possibly 
it's not correct as it sounds as if you're using something from one 
build with another. You certainly wouldn't see it getting far enough to 
recurse if it were the case.

If you build the and run the debug version of bbstoreaccounts under gdb 
with

   cd bin/bbstoreaccounts
   make
   cd ../../debug/bin/bbstoreaccounts
   gdb bbstoreaccounts

then in gdb, type

   run -c <configfilename> create 21

for example (with <configfilename> replaced with the config file you're 
using). It should then crash, then type

   bt

to see the backtrace, and it should be more accurate.
