Bug ID: 31161
Summary: potential Memory in stabs.c
Product: binutils
Version: 2.32
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org

Target Milestone: ---
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 stabs.c. The red text
illustrates the steps that generate the bug.
As shown in the diagram, in the function parse_stab, a block of memory is
allocated for dhandle->current_file by calling the function debug_set_filename.
After calling parse_stab, the memory of dhandle->current_file is not freed.The
memory of dhandle->current_file will 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.
