           Summary: ARM/THUMB thunk calls broken
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal

When compiling ARM programs in THUMB mode, thunks use a 'b' instruction to branch to 
the target function. Since the 'b' instruction has a very limited adressing range (+/- 256 
bytes), and the thunk and its target function are placed in different sections, linking errors 
are very common: 
 
csr_camerastatus.o: In function `non-virtual thunk [nv:-24] to 
CSR_CAMERASTATUS::SetProtocolError(ProtocolErrorHandler::EPROT_ERR_VAL)': 
csr_camerastatus.o(.gnu.linkonce.t._ZThn24_N16CSR_CAMERASTATUS16SetProtocolErrorEN20ProtocolErrorHandler13EPROT_ERR_VALE+0x2): 
relocation truncated to fit: R_ARM_THM_PC11 
CSR_CAMERASTATUS::SetProtocolError(ProtocolErrorHandler::EPROT_ERR_VAL)
