+OpenJDK JVM segfaults on qemu-sh4 (regression)
+
+Some of the recent changes introduced a regression which makes the OpenJDK JVM crash on qemu-sh4:

+
+So, OpenJDK doesn't have a SH-specific implementation of the JVM, it just
+uses the Zero variant, which is a pure C++ implementation of the JVM.
+
+The same implementation is used on any other architecture like older ARM
+(< ARMv7). I just tested it on ARMv4T and it doesn't crash there on
+qemu-user.
+
+However, SH4 is special due to its implementation of atomics in user
+space called gUSA for which support to qemu-user has been recently
+added by Richard Hendersson. Maybe the problem lies there.
+
+> A backtrace QEMU after the segv would be useful here.
+
+I forgot what the proper procedure is for running qemu-user inside
+GDB. Could you help me with that?

+Either call directly:
+
+  gdb --args qemu-foo <userspace args>
+
+Or alternatively:
+
+  qemu-foo -g 1234 <userspace args>
+
+And then:
+
+  gdb qemu-foo -p <pid of qemu-foo>
+
+And finally attaching to the gdbstub:
+
+  gdb-multiarch -ex "target remote localhost:1234"
+  c
+
+Or just make sure your environment is generating core dumps you can
+backtrace at leisure:
+
+  gdb qemu-foo core
