heap use after free in xcoff_archive_info_eq
Using an input file objalloc memory for anything that isn't created
when opening the bfd is not a good idea. The problem is that this
memory can disappear if bfd_free_cached_info is called or when bfd
closes files in order to keep the number of open files reasonable.
bfd/
* xcofflink.c (xcoff_get_archive_info): Allocate xcoff_archive_info
on the output bfd objalloc memory.
ld/
* testsuite/ld-scripts/sysroot-prefix.exp (single_sysroot_prefix_test):
Log $scriptname.
