[Octave-bug-tracker] [bug #52061] Memory issue whenever Java JVM is used

[Dmitri A. Sergatskov]

Follow-up Comment #19, bug #52061 (project octave):

I resurected some old (Core 2 duo) laptop and it also does NOT 
crash. So it looks like the newish CPUs are causing the problem.

On i7 I compiled a minimal version

../configure JAVA_HOME=/usr/lib/jvm/java-9  CFLAGS="-ggdb3 -O0 -pipe"
CXXFLAGS="-ggdb3 -O0 -pipe" FFLAGS="-ggdb3 -O0 -pipe"
--enable-address-sanitizer-flags --without-qt  --without-fltk --without-opengl
--without-osmesa --disable-docs

so I do not need top bother with LD_PRELOAD=libasan.so
(which seems to be changing things a little).
Then running under gdb I get:


octave:1> __java_init__

vm_version_x86.cpp:530 is:

 get_cpu_info_stub(&_cpuid_info);

The file is attached.
