Bug ID: 29262
Summary: A Potential Memory Leak Bug
Product: binutils
Version: 2.34
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org

diagram of memory leak bug
Hi, I found a potential memory leak bug in the project source code of binutils,
I have shown the execution sequence of the program that may generate the bug on
a diagram which is added to the attachment.
The text in red illustrates the steps that generate the bug
The red arrows represent call relationships
The green text illustrates the files and functions whose code snippets are
located below the green text.
In short, the key to the bug is the third step in the diagram. In the third
step, when the true branch is selected, the program will directly "return
FALSE" instead of doing a free operation on 's',and the function call in the
condition statement does not do a free operation on 's', which leads to a
memory leak.
I look forward to your reply and thank you very much for your patience!
