Hi,I found a potential null pointer dereference bug in ld/ldlang.c,and I have
shown the execution sequence in an image, which can be accessed through the
link below:

The red text illustrates the steps that generate the bug, and the file path can
be seen in the blue framed section.

I also find that there is check whether os is NULL(shown in the image above) at
line 3874, just a little behind line 3846. 

Although the code shown is for version 2.32 but this potential bug is still
exist in the current version.Would you can help to check if this bug is true?
Thank you for your effort and patience!
