            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.
