Summary: potential memory leak in parse_args
Product: binutils
Version: 2.34
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: liuyingying19 at huawei dot com

Test case:
#include <stdio.h>

Direct leak of 5664 byte(s) in 1 object(s) allocated from:
#0 0x7fedf6816860 in __interceptor_malloc
../../.././libsanitier/asasn/asan_malloc_linux.cc:62
#1 0x560879e0b151 in parse_args (/usr/bin/riscv32-unknown-elf-ld+03d151)
binutils version 2.34
Checked on the source code, I did not see any free action on below shortopts,
longopts, really_longopts variable.
ld/lexsup.c
shortopts = (char *) xmalloc (OPTION_COUNT * 3 + 2);
longopts = (struct option *)
xmalloc (sizeof (*longopts) * (OPTION_COUNT + 1));
really_longopts = (struct option *)
malloc (sizeof (*really_longopts) * (OPTION_COUNT + 1));
