The problem however is in the C++ name demangler, which is part of the libiberty library. This library is maintained by the gcc project, not the binutils project.

https://sourceware.org/bugzilla/show_bug.cgi?id=23056 Nick Clifton changed: What|Removed |Added Status|UNCONFIRMED |ASSIGNED Last reconfirmed||2018-04-18 CC||nickc at redhat dot com Ever confirmed|0 |1 --- Comment #1 from Nick Clifton --- Hi Sergej, Thanks for reporting these bugs. Unfortunately I cannot reproduce them. Are you sure that the command line is correct ? When I run "gprof $file" I just get an error message: "not in executable format". I suspect that this is because I am running the tests on a 64-bit x86_64 host... Are you able to reproduce the failures in a 64-bit environment ? Also gprof normally needs a gmon.out file to go along with the executable, and this file is missing from the zip file you uploaded. I suspect that the "global-buffer-overflow" failure has already been addressed by the fix for PR 23055. However the "heap-buffer-overflow" bug is in the gprof sources, and presumably still exists.

Bug ID: 23079
Summary: Multiple PREVAILING_DEF_IRONLY for a same symbol in an
archive
Product: binutils
Version: 2.31 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: mliska at suse dot cz
Target Milestone: ---
Let's consider:
$ cat 1.i
int igt_subtest_jmpbuf, viewport;
$ cat 2.i
int igt_subtest_jmpbuf, viewport;
$ gcc -flto 1.i -c
$ gcc -flto 2.i -c
$ ar cru libx.la 1.o 2.o
$ ranlib libx.la
$ cat main.i
int igt_subtest_jmpbuf;
extern int viewport;
int main()
{
return igt_subtest_jmpbuf;
}
$ gcc main.i libx.la -flto
lto1: fatal error: multiple prevailing defs for ‘viewport’
compilation terminated.
lto-wrapper: fatal error: gcc returned 1 exit status
compilation terminated.
/usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: error:
lto-wrapper failed
collect2: error: ld returned 1 exit status
It's caused by fact that:
$ cat main.res
3
main.o 2
190 57d43a0e4f2e4898 PREVAILING_DEF main
194 57d43a0e4f2e4898 PREVAILING_DEF_IRONLY igt_subtest_jmpbuf
libx.la@0xcc 2
188 65b5ba79fd3c2703 PREVAILING_DEF_IRONLY viewport
190 65b5ba79fd3c2703 RESOLVED_IR igt_subtest_jmpbuf
libx.la@0x9d8 2
188 253018f931e7b9de PREVAILING_DEF_IRONLY viewport
190 253018f931e7b9de RESOLVED_IR igt_subtest_jmpbuf
While ld.gold does:
$ cat main.res
cat main.res
1
main.o 2
190 f4c25c288a258244 PREVAILING_DEF main
194 f4c25c288a258244 PREVAILING_DEF_IRONLY igt_subtest_jmpbuf
If I modify main.i to:
$ cat main.i
int igt_subtest_jmpbuf;
extern int viewport;
int main()
{
return igt_subtest_jmpbuf + viewport;
}
Then it's all fine with BFD resolution file looking as follows:
$ cat main.res
3
main.o 3
190 aa0f078bbef97098 PREVAILING_DEF main
194 aa0f078bbef97098 PREVAILING_DEF_IRONLY igt_subtest_jmpbuf

https://sourceware.org/bugzilla/show_bug.cgi?id=23056 --- Comment #2 from Sergej Schumilo --- Hi Nick, yes we can reproduce both ASAN reports on a 64-bit Linux environment (Ubuntu 16.04.2 LTS) using the attached 64-bit ASAN executable with only one command line argument (global-buffer-overflow or heap-overflow-0x004fae16). To reproduce our findings, you don't need an additional file or to pass an additional command line argument to gprof. The ASAN executable of gprof is based on the source files of binuitils-2.30-15ubuntu1.

Gold works only because it treats COMMON symbol like definition:

#include
int igt_subtest_jmpbuf;
int main ()
{
printf ("igt_subtest_jmpbuf: %d\n", igt_subtest_jmpbuf);
return 0;
}
[hjl@gnu-tools-1 nolto]$ cat x.i
int igt_subtest_jmpbuf = -1;
[hjl@gnu-tools-1 nolto]$ cat y.i
int igt_subtest_jmpbuf = -2;
[hjl@gnu-tools-1 nolto]$ make

gcc -c -o y.o y.i
