Memory Leak in ldwrite.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 ldwrite.c. The red
text illustrates the steps that generate the bug.

As shown in the diagram, in the function build_link_order, the variables
link_order->u.data.contents and link_order->u.reloc.p are allocated memory.
However, they are not freed, which will lead to a memory leak.

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.
