Question

I have the following code snippet

fscanf( fSettings, "%s", szLine );  
bool x = separateBool   ( szLine );
gSettings.useBE = x;

szLine contains useBE=1. x is set to true and the VS2010 Pro watch sees it. However, after value is assigned to gSettings.useBE in the last line, the value of gSettings.useBE is still visible as false! I have no idea how this is happenning. VS2010 SP1 installed. Many thanks for any input.

Edit:
The separateBool is the following function:

  inline 
  bool separateBool( const char * szStr )   
  {
       std::vector<std::string> res = split(szStr, '=');
       if ( res.size() < 2 )
          ;  /* error */
       return (str2int( res[1] ) == 1 );        
  };

The toy version of the “algorithm”

bool a = false;
bool b = false;
b = separateBool    ( szLine );
a = b;
a = separateBool    ( szLine );

does everything right.

Changing the Struct Member Alignment in Properties->C/C++->CodeGeneration to 4 bytes from the original 8 bytes makes the trick. But I still have no idea why…
