Re: #570889 ant: FTBFS on kfreebsd-* and hppa: Bus error

The file, which have to be copied, have size 1701,

Linux and FreeBSD.
When the 2nd page of that file would be accessed, it would
generate SIGBUS.

The question is of course whether it really happens and why ?

File descriptor 0 is standard input and you can't mmap that.
You should also check the return of mmap.
Could you please provide a new test case?

Please really try to run the example code,
for me (pagesize 4096) it gives:

0x800636000 32
0x800636000 0
Bus error

The example code just illustrates what might happen in
failure of ant. The affected architectures directly in
ant build have been only kfreebsd-* and hppa.

Now it looks like wider problem - #571532, #571542, #571397.
