Not sure, maybe (Marc pointed that out ot me once) it is the same, why 
the IDE does take the address of RAISE_Exception, and set the break at 
the address.

GDB looks at the assembler of the function and makes a decision where 
the prologue ends. With FPC omitting the stackframe it may get that wrong.

Though I have used the

  b FPC_RAISEEXCEPTION
myself, and it had worked, but it may depend on versions, etc.

Try
info address
b *0x8072f25

--------------

here is output from gdb I just tried

(gdb) b FPC_RAISEEXCEPTION
Breakpoint 1 at 0x40da33: file ../inc/except.inc, line 195.
(gdb) info address  FPC_RAISEEXCEPTION
Symbol "FPC_RAISEEXCEPTION" is at 0x40da20 in a file compiled without debugging.
(gdb)


info address is 19 bytes earlier
In my case that is correct (looking at disaasemble), but my FPC was build with -O1
