This patch performs a run-time test that a shared libbfd.so has been compiled with the same size bfd_vma as that of apps using the library. On a 32-bit host it is easily possible to have one libbfd.so compiled to support 64-bit targets (or configured with --enable-64-bit-bfd) while another only supports 32-bit targets. The two libraries will have differently sized bfd_vma types, and if the wrong one is loaded all sorts of weird behaviour might be seen. bfd/ PR 23534 * init.c (BFD_INIT_MAGIC): Define.

SYNOPSIS
|
|
size_t bfd_init (void);

DESCRIPTION
|
|
This routine must be called before any other BFD function to
|
|
initialize magical internal data structures.
|
|
Returns a magic number, which may be used to check
|
|
that the bfd library is configured as expected by users.

However, someday it may be needed, so keep it around. */
