[Bug debug/43989] New: g++ missing the debug information of local static variable


g++ misses the debug information of local static variable but gcc doesn't.

gcc version: 4.1.2 20080704 (Red Hat 4.1.2-44)
g++ version: 4.1.2 20080704 (Red Hat 4.1.2-44)
OS version: Red Hat Enterprise Linux Client release 5.3 (Tikanga)

code stored in the file myTest.c:

void CStyleFunction()
{
  static int variableInFunction = 2;
}

int main()
{
   static int varaibleInMain = 1;
   CStyleFunction();
   return 0;   
}

gcc build command: gcc -g myTest.c -o c.out
g++ build command: g++ -g myTest.c -o cpp.out

Then use the command to print out the debug information:
objdump -W c.out
objdump -W cpp.out

It can be seen that the debug information of static local variable
'variableInFunction' and 'variableInMain' is missing in cpp.out while it isn't
in c.out. As a result, gdb can show the value of the former while it can't show
the value of the latter.
