internal compiler error: Segmentation fault

[bibhukalyana]

Hi everyone,
I am using qt 4.7.3. Since last one month i am getting "internal compiler error: Segmentation fault" error. During build I am getting this error. It is not coming frequently.
For the same code in one system i am getting this error but in different system it is working fine(qt version is same).

A: if(a > 0)
       continue;
 
 
B: if(a > 0)
    {
       continue;
    }

A: if(a > 0)
       continue;


B: if(a > 0)
    {
       continue;
    }

To copy to clipboard, switch view to plain text mode 

For A i am getting error and for B no error.

Can anybody please tell me about this error ? Is my qt corrupted or there is some other issues in my pc ?

thanks,
bibhu.
