octave exited with signal 11


Their is no segfault when using command-line interface. The octave is compiled
from sources. The same behavior is observed on Ubuntu 18.04 with Qt5 gui and
CentOS 7 with Qt4 gui. Ubuntu crash report is 20MB long. The stack trace from
it is attached. The problem is reproduced also with much shortened
make_int2.cc file, which is also attached.
