Re C bug 2035 -

[John Smith]

I think this is essentially the same as bug 2035, but trimmed down a bit.

The following bit of code generates a gcc internal error:
 
void  mainx(void) {

  double  v;

  struct {
    float  f;
  } d;

  v = 1.0 ; 
  d.f=*(float *)&v;

}

prompt:> gcc -O1 -c main.c
main.c: In function `mainx':
main.c:13: Internal compiler error in `extract_bit_field', at
expmed.c:1082
Please submit a full bug report.
See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.

(Using gcc 2.95.3 on i586-pc-linux-gnulibc1)


My real question is: what should happen?
Should the compiler generate an ordinary error message, or should it 
carefully store things in memory and interpret the code as best it can?

Is the code actually illegal, or merely dodgy?
