Hi enggakshat, What version of GCC are you using? What programming language from GCC are you using? Ah, by your title, it appears you are using C -- not C++, FORTRAN, Ada, Java 1.4, D Programming Language, or some other language supported by GCC. What hardware platform are you using? What operating system are you using? What command line arguments for GCC's gcc tool chain driver are you using? Can you provide some COMPILABLE minimal example code that reproduces the problem? Thanks, --Eljay
