I have found a bug in the GNU C compiler version 2.7.2.1 on
`i486-linux'.  The output of "gcc -v" is

    Reading specs from /usr/lib/gcc-lib/i486-linux/2.7.2.1/specs
    gcc version 2.7.2.1

When I feed the appended (and already preprocessed) input file via the
command "gcc bug.c" into gcc, I got the following output.

    bug.c: In function `main':
    bug.c:33: warning: initialization makes pointer from integer without a cast
    bug.c:33: incompatible types in initialization
    bug.c:34: incompatible types in initialization
    bug.c:36: incompatible types in initialization
    bug.c:37: incompatible types in initialization
    bug.c:39: incompatible types in initialization
    bug.c:41: incompatible types in initialization
    gcc: Internal compiler error: program cc1 got fatal signal 6

The last line indicates a bug as "reliable compilers never crash".

I hope, this bug report helps you to improve GCC.
