[Octave-bug-tracker] [bug #52903] segfault running testsuite on ARM: ov-class.cc-tst

[Colin Macdonald]

Follow-up Comment #2, bug #52903 (project octave):

Thanks for you help!  As far as I can tell its a local problem on that one
machine, b/c I tried another ARM machine and I cannot reproduce on there.  I'm
sorry for wasting your time.  I guess this can be closed?

For the record, here's what happened on
"arm03-packager01.cloud.fedoraproject.org":

Both of these segfault:

./run-octave --eval "usejava('jvm')"
octave --eval "usejava('jvm')"


Here octave is 4.2.1 from the fedora package.  And ./run-octave is a hg tip
from day or two ago.

Here's a bit of configure:

configure: WARNING: JAVA_HOME environment variable not initialized. 
Auto-detection will proceed but is unreliable.

I'm not much good with gdb but in case this helps:
