Bug ID: 21787
Summary: Heap-use-after-free in bfd_cache_close
Product: binutils
Version: 2.30 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils

testcase
A heap-use-after-free is triggered when the provided file is scanned using
`./objdump -x use-after-free`. All targets must be enabled; I believe the bug
is in the XCOFF archive format.
I used ASAN to detect the crash. If you have trouble reproducing this (valgrind
may work as well, but I haven't checked), let me know.
