Bug ID: 23601
Summary: Memory leak dwarf.c
Product: binutils
Version: 2.31
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: tianxiao.gu at gmail dot com
Target Milestone: ---
Created attachment 11220
--> https://sourceware.org/bugzilla/attachment.cgi?id=11220&action=edit
File for reproducing the leak
Our fuzzing tool has recently detected a memory leak of objdump on binutils
2.31. We cannot verify the leak on the HEAD due to the following building
error.
./common/traits.h:96:33: error: no member named 'value' in 'IsRelocatable<type
*>'
Reproduce:
1. Download and unzip the attached file 299.zip
2. Run `objdump -g 299`
Output:
