mthread binary

On 32 bits agent/program, the lineNumber service cannot get the source mapping for an address in main() routine range for the main thread context. It returns None.

*** how to reproduce ***

- start a 32 bit tcf agent.
- start the attached mthread program built for 32 bits.
- interrupt all threads
- attach to main thread
- get the source line number for startAddress = 0x8048835, endAddress=0x8048836 (before the call to sleep()) => returns None

Previous addresses are bad.
Right addresses of mapToSource call are : 
startAddress=0x804883a, endAddress=0x804883b
