big issues with state machine loading

Hi all,

We are currently evaluating orocos toolchain 2.7rc3
My configuration is :

- boost-1.53.0
- gcc-4.7.3

The test sample is the helloworld.cpp from the tutorials; here is the 
state machine script:

StateMachine States {

         initial state initState
         {
                 entry
                 {
                 }

                 transition select Final
         }
         final state Final
         {
                 entry
                 {
                 }

//
         }
}

RootMachine  States sTates


I am testing on 2 target architectures, the first one is intel and the 
second, arm
The bug I am mentioning here occur one the real targets, as well as with 
qemu user.

On intel, comments (both "//" and "/* ...*/" )in state machine are 
detected as errors:

Hello [R]> scripting.loadStateMachines("statemachine.osd")
6.129 [ Info   ][ScriptingService::loadStateMachine] Parsing file 
statemachine.osd
6.247 [ ERROR  ][ScriptingService::loadStateMachine] statemachine.osd 
:Parse error at line 18: Syntactic error: Exptected ending '}' at end of 
state ( or could not find out what this line means ).
  = false


On arm, that directly leads to a SIGSEGV. I do not have a backtrace for 
now, unfortunately.


I would like to add that the bug is also reproducible with orocos-1.1x 
and boost-1.35, letting me think
that this could be due to the compiler version. Our investigations have 
failed to identity the cause,
and I wanted to try with latest orocos version before posting.

Regards
Thierry
