Hi,

This is version 2 of the patch I posted in the following thread:

http://sourceware.org/ml/gdb-patches/2012-07/msg00422.html

dwarf_block.SIZE should be size_t to accept larger data blocks in case
of DW_FORM_block, since the size of the length of a DW_FORM_block is
not specified and can be anything encoded in a uleb128. The
dwarf2_loclist_baton and dwarf2_locexpr_baton SIZE members also need to
be made size_t just to eliminate splint warnings.

I haven't been able to figure out a test case to reproduce this
problem, so I have stuck to ensuring that it does not cause a
regression in the testsuite. I have also done another pass through the
code to make sure that there are no other places that need fixing as a
result of this.

Regards,
Siddhesh
