[Bug target/18863] New: ICE in find_reloads

[simonb at wasabisystems dot com]

Trying to compile a simple program results in:

zlib.i: In function 'huft_build':
zlib.i:26: internal compiler error: in find_reloads, at reload.c:3911
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

when compiled with
  gcc version 4.0.0 20041206 (experimental)

Here is the test program (reduced from some code in the zlib compression
library):

void huft_build (const int *, int *);

struct inflate_huft_s {
  union {
    char Exop;
  } word;
  int base;
};

void huft_build(e, v)
const int *e;
int *v;
{
  int k;
  struct inflate_huft_s r, *u[15];

  k = 0;
  u[0] = 0;

  for (; k <= 16; k++)
  {
      u[0][0] = r;
      if (*v < 19)
        r.word.Exop = (char)(e[*v] + 64);
  }
}
