Public bug reported:
In qemu user mode, for hppa and sparc64 targets, the parameter of the
dup3 is not passed correctly when it contains the O_CLOEXEC flag.
When the attached program runs, the expected output is:
errno=9=EBADF
How to reproduce on hppa:
- Compile the program: hppa-linux-gnu-gcc-5 -O -Wall -static testdup3.c -o
testdup3-hppa
- Set environment variables for running qemu-hppa.
- ~/inst-qemu/2.9.0/bin/qemu-hppa testdup3-hppa
errno=22=EINVAL
testdup3.c:54: assertion 'errno == EBADF' failed
How to reproduce on sparc64:
- Compile the program: sparc64-linux-gnu-gcc-5 -O -Wall -static testdup3.c -o
testdup3-sparc64
- Set environment variables for running qemu-sparc64.
- ~/inst-qemu/2.9.0/bin/qemu-sparc64 testdup3-sparc64
errno=22=EINVAL
testdup3.c:54: assertion 'errno == EBADF' failed
