Input leading to memory leak
There is a memory leak in copy_relocations_in_section in objcopy.c that we
found through fuzzing (confirmed with ASAN/LSAN).
relpp is allocated but never freed when relcount != 0, strip_symbols !=
STRIP_ALL, and relsize > 0.
I appended the testcase as an attachment; we used the following command to
invoke objcopy:
./objcopy --dump-section .text=/dev/null objcopy_input /dev/null
