Re: Fix an undefined behaviour in the BFD library's DWARF parser
Using an unsigned int cast (to 32 bits) on a pointer difference (of
possibly 64 bits) is wrong. Even though it will work on all real
object files, the fuzzers will eventually find this hole.
PR 28687
* dwarf1.c (parse_die): Cast pointer difference to size_t.
Catch another possible pointer overflow.
