Whoa there!  Looking at how these variables are used, I just noticed
that this code is broken:

> +	      uint32_t addr32;
> +
> +              if (target_read_memory (ir.addr, (gdb_byte *) &addr32, 4))

You're reading from target memory (which is little endian) into a
32-bit variable in host memory (which is big endian).  That's wrong!
And the process record stuff is full of it.

Please fix this by reading into a gdb_byte buffer and using
extract_{signed|unsigned}_integer(), or use
read_memeory_{unsigned_}integer().
