Memory Leak in elfxx-x86.c

Hi, I found a memory leak bug in the source code of binutils, and I have shown 
the execution sequence below. This bug exists in the file /bfd/elfxx-x86.c. The
red text illustrates the steps that generate the bug.
As shown in the diagram, in the function _bfd_x86_elf_link_hash_table_create, a
block of memory is allocated for the variable ret->loc_hash_memory. However, if
ret->loc_hash_table fails to be created, it will result in returning NULL,
potentially causing a memory leak vulnerability.
Although reported bug trace is for version 2.32 but i've check this bug still
existing in latest version.

can you help to check if this bug is true? thanks for your effort.
