The LPC2xxx can map SRAM and the Boot Block (and on some processors,
off-chip memory) to the interrupts vectors at 0x0, replacing the view of
the user flash at 0x0.

Have a look at your LPC's datasheet, particularly the Memory Mapping
Control part of the System Control Block documentation. I bet if you switch
the MEMMAP register to 0x1 to view user flash, you would see what you expect.
