Bug ID: 94157
Summary: [10 Regression] error: lto-wrapper failed with
-Wa,--noexecstack -Wa,--noexecstack
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Using gcc10 package I see a strange error:
$ echo "int main() {}" > x.c
$ gcc -flto -c x.c
$ gcc -Wa,--noexecstack -Wa,--noexecstack x.o
/usr/lib64/gcc/x86_64-suse-linux/10/../../../../x86_64-suse-linux/bin/ld:
error: lto-wrapper failed
collect2: error: ld returned 1 exit status
$ gcc -Wa,--noexecstack x.o
[fine]
I can't reproduce that with locally built GCC and gcc9 package seems fine.

Seems you are using the latest binutils ld, right?
It's the newly added warning which tells that usage of executable stack is a
potential security issue:
