           Summary: local variable used before set
           Product: xorg
           Version: 6.8.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Lib/GLX
        AssignedTo: xorg-bugzilla-noise at freedesktop.org

Hello there,

I just tried to compile X11R6.8.1 with the most excellent Intel C
8.1 compiler, on a Linux Fedora Core 3 box. The compiler said

glxcmds.c(1508): remark #592: variable "req" is used before its value is set

The source code is in file

./lib/GL/glx/glxcmds.c

The source code is

    if ( (priv->majorVersion > 1) || (priv->minorVersion >= 3) ) {
    xGLXQueryContextReq * req;

    req->reqType = opcode;
    req->glxCode = X_GLXQueryContext;
    req->context = (unsigned int)(ctx->xid);
    }

Clearly, the compiler is correct. Suggest init req before first use.
