Ignore what said about a missing instruction.  It is there.

The problem is simple.  The fault is caused by this code:

struct foo {
  void *entry[40];
} __attribute__ ((aligned(32)));

This gives a value of 256 for rli->offset_align.  The bit field for
off_align in field is 8 bits.  Thus, the rli alignment requirement exceeds
the maximum value for DECL_OFFSET_ALIGN (field).

What to do?
