Public bug reported:
qemu-user v6.0.0-rc5, built in static mode, will crash for certain ppc
binaries. It seems to have something to do with glibc for some Centos
versions. The problem is easiest to see with statically-linked
binaries.
The attached Dockerfile shows how to produce a ppc binary that will
crash qemu-user. Here is how to reproduce the problem:
$ uname -m
x86_64
$ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
$ docker build -t qemu-bug:centos -f Dockerfile.centos .
$ docker run --rm -it -v$PWD:$PWD -w$PWD qemu-bug:centos cp /helloworld-
centos.static.ppc .
$ qemu-ppc-static --version
qemu-ppc version 5.2.95 (v6.0.0-rc5)
