Actually this is the intended behaviour.  The --stop-address option 
specifies the address at which objdump should *stop* displaying data.  
So when objdump reaches address 50c5f it stops and does not display
the disassembly for that address.

In order to display the entire disassembly of a specific region you
need to set the stop address to one more than the last address of the
region concerned.  So in your example:

  $ objdump --start-address=0x50c40 --stop-address=0x50c60 -d

should work.
