Bug ID: 21281
Summary: Cannot compile Binutils with ASAN because of a memory
leak bug in sysinfo.c
Product: binutils
Version: 2.29 (HEAD)
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: thuanpv at comp dot nus.edu.sg
Target Milestone: ---
Dear all,
I would like to report a potential memory leak in Binutils' sysinfo utility
which prevents us from compiling the toolset with ASAN.
I face the issue on Ubuntu 64-bit 14.04 and Binutils version is
commit 09220eae9df07c40d206a35e6caaecba92ab8f46
Author: GDB Administrator <[email protected]>
Date: Tue Mar 21 00:00:24 2017 +0000
Automatic date update in version.in
I configured and compiled Binutils using the following commands using clang-3.5
mkdir build-asan; cd build-asan
CC=clang CFLAGS="-DFORTIFY_SOURCE=2 -fstack-protector-all
-fsanitize=undefined,address -fno-omit-frame-pointer -g -Wno-error"
../configure --disable-shared --disable-gdb --disable-libdecnumber
--disable-readline --disable-sim
make clean all
Here is the error message I got:
=================================================================
==92396==ERROR: LeakSanitizer: detected memory leaks
