[Qemu-devel] [Bug 1659901] [NEW] Regression: SIGSEGV running Java

[Rich DiCroce]

Public bug reported:

I have a build script that bootstraps a Debian armhf image. Part of the
process involves running a Java program while inside a chroot. I am
using Debian's qemu-user-static package to run the armhf Java binary on
an amd64 system.

qemu-user-static version 1:2.7+dfsg-3~bpo8+2 works fine. Version
1:2.8+dfsg-1~bpo8+1 always causes Java to crash with a SIGSEGV. The
location of the crash appears to be random and hasn't been the same
twice.

I am using the Azul Systems Zulu Embedded Java runtime, rather than the
regular OpenJDK runtime, because the Zulu runtime has an arm32 JIT
whereas OpenJDK is interpreter-only on arm32.

I can reproduce the problem easily by mounting the image created by my
build script and executing "java -XshowSettings -version" in a chroot. I
can give you the image if that would help debug the problem.
