Hi!
We're having an odd issue on Debian/m68k with both firebird3.0 and openjdk-8
hanging during build until the build process is killed.
With openjdk-8, it looks like this [1]:
checking if we are using ecj as javac... [debian/buildwatch.sh] compiler/java/jar running ...
[debian/buildwatch.sh] compiler/java/jar running ...
[debian/buildwatch.sh] compiler/java/jar running ...
[debian/buildwatch.sh] compiler/java/jar running ...
[debian/buildwatch.sh] compiler/java/jar running ...
[debian/buildwatch.sh] compiler/java/jar running ...
E: ABORT: Received INT signal (requesting cleanup and shutdown)
Which means that running "javac" just hangs forever. It seems that Thorsten Glaser
has seen this problem in the past before [2] but I don't know whether he ever
managed to fix it. The openjdk-8 package that currently exists for m68k was
actually re-packed by me by replacing libjvm.so from Andreas Schwab's build
(see below why).
And with firebird3.0 we have [3]:

(hangs here)
In both cases, attaching to the running process shows we're hanging in the futex() system call:
root@mama:~# strace -p 28109
strace: Process 28109 attached
futex(0xc5aff4f8, FUTEX_WAIT, 28113, NULL
For the openjdk-8, the issue can be worked around by replacing libjvm.so with a copy
from Andreas Schwab's openjdk-8 build for openSUSE/m68k, so it seems like the JVM
gets miscompiled on Debian/m68k.
Something similar applies to firebird3.0. When building the package in an older
change root (with glibc2.19), the problem [4].
I have tested both on Aranym and qemu-m68k, both show the same behavior. I have
also rebuilt glibc with an upstream patch from Andreas which fixed 64-bit
atomics in glibc [5] but that didn't help either. I also tried rebuilding
glibc on Aranym to make sure it wasn't miscompiled on qemu-m68k on the
buildds.
Does anyone have a suggestion where to look for problems here? I am really
running out of ideas. It's one of the weirdest problems I have ever seen.
