https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209599 --- Comment #6 from Andrew Smith <iamasmith.home@gmail.com> --- Following a few false starts without being able to get gdb to unwind the st= ack trace I decided to invoke the test directly with -XX:+ShowMessageBoxOnError= so I could hop into gdb directly. It's identified Unsafe_GetNativeByte as the cause of the SIGSEGV but this is somewhat obfuscated by it being macro generated. Just thought I had better test this with PCH turned off before I proceed so next report will be results of that. /usr/ports/java/openjdk8/work/openjdk/build/bsd-x86_64-normal-server-slowde= bug/images/j2sdk-image/bin/javac -J-ea -J-esa -J-Xmx512m -J-Dtest.vm.opts=3D'-ea -esa -Xmx512m'=20 -J-Dtest.class.path.prefix=3D/usr/ports/java/openjdk8/work/openjdk/build/bs= d-x86_64-normal-server-slowdebug/testoutput/jdk_core/JTwork/classes/1/java/= nio/MappedByteBuffer:/usr/ports/java/openjdk8/work/openjdk/jdk/test/java/ni= o/MappedByteBuffer -J-Dtest.jdk=3D/usr/ports/java/openjdk8/work/openjdk/build/bsd-x86_64-norma= l-server-slowdebug/images/j2sdk-image -J-Dtest.timeout.factor=3D4.0 -J-Dtest.src.path=3D/usr/ports/java/openjdk8/work/openjdk/jdk/test/java/nio= /MappedByteBuffer -J-Dtest.compiler.opts=3D=20 -J-Dcompile.jdk=3D/usr/ports/java/openjdk8/work/openjdk/build/bsd-x86_64-no= rmal-server-slowdebug/images/j2sdk-image -J-Dtest.classes=3D/usr/ports/java/openjdk8/work/openjdk/build/bsd-x86_64-n= ormal-server-slowdebug/testoutput/jdk_core/JTwork/classes/1/java/nio/Mapped= ByteBuffer -J-Dtest.class.path=3D/usr/ports/java/openjdk8/work/openjdk/build/bsd-x86_6= 4-normal-server-slowdebug/testoutput/jdk_core/JTwork/classes/1/java/nio/Map= pedByteBuffer -J-Dtest.java.opts=3D=20 -J-Dtest.src=3D/usr/ports/java/openjdk8/work/openjdk/jdk/test/java/nio/Mapp= edByteBuffer -J-Dtest.tool.vm.opts=3D'-J-ea -J-esa -J-Xmx512m' -d=20 /usr/ports/java/openjdk8/work/openjdk/build/bsd-x86_64-normal-server-slowde= bug/testoutput/jdk_core/JTwork/classes/1/java/nio/MappedByteBuffer -classpath /usr/ports/java/openjdk8/work/openjdk/build/bsd-x86_64-normal-server-slowde= bug/testoutput/jdk_core/JTwork/classes/1/java/nio/MappedByteBuffer:/usr/por= ts/java/openjdk8/work/openjdk/jdk/test/java/nio/MappedByteBuffer:/usr/ports= /java/openjdk8/work/openjdk/build/bsd-x86_64-normal-server-slowdebug/images= /j2sdk-image/lib/tools.jar -sourcepath /usr/ports/java/openjdk8/work/openjdk/jdk/test/java/nio/MappedByteBuffer -XDignore.symbol.file=3Dtrue /usr/ports/java/openjdk8/work/openjdk/jdk/test/java/nio/MappedByteBuffer/Tr= uncate.java root@testbuild1:/usr/ports/java/openjdk8/work/openjdk/build/bsd-x86_64-norm= al-server-slowdebug/testoutput/jdk_core/JTwork/classes/1/java/nio/MappedByt= eBuffer # java -XX:+ShowMessageBoxOnError -cp .
