Public bug reported:
This can be simply reproduced by compiling and running the attached C
code (readdir-bug.c) under 32-bit user-static qemu, such as qemu-arm-
static:
# Setup docker for user-static binfmt
docker run --rm --privileged multiarch/qemu-user-static:register --reset

I was hit by this issue when I tried to run some Java program. And it
turns out jdk sets the buf to NULL:

To reproduce it, compile the attached crash.c under aarch64 to a.out and
execute on x86_64
qemu-aarch64-static ./a.out
It will print the following and crash:
socket=3
qemu:handle_cpu_signal received signal outside vCPU context @ pc=0x60038cd6
qemu:handle_cpu_signal
Thanks Peter for your information.
I was hit by the bug when trying to compile bazel (a build system open-
sourced by Google: https://bazel.build) and the code is at
https://github.com/bazelbuild/bazel/blob/master/third_party/ijar/mapped_file_unix.cc#L116
Of course I can send PR to fix that in

Title:
qemu-arm-static read() doesn't accept mmap address as destination
Public bug reported:
When read() function takes an mmap'ed address as output buffer, it

The following code works for qemu-system-arm, but not for qemu-arm-
static.
QEMU version affected: latest release 2.12.0.
