C++/stl_deque problem

Hey all,

I'm messing some with the 1.3.x code trying to make a tool using the 
bincimap-updatecache.cc and after Mailbox->createMessage and commiting 
it I get this just Mailbox->close()ing:

(gdb) bt
#0  0x4011a251 in kill () from /lib/libc.so.6
#1  0x40119e85 in raise () from /lib/libc.so.6
#2  0x4011b678 in abort () from /lib/libc.so.6

#10 0x08049f61 in _start () at ../sysdeps/i386/elf/start.S:102

I don't know C++ as well as I'd want, what have I missed?
