On starting octave with its GUI, if one immediately moves the window right after it has appeared, one gets % gdb81 /usr/local/libexec/octave/4.4.0/exec/amd64-portbld-freebsd12.0/octave-gui octave-gui.core warning: Unexpected size of section `.reg-xstate/100808' in core file.

Moin moin I think this is foremost a problem in octave, not Qt. Stephen, can you take a look? mfg Tobias
Although one other person has reported this problem to me, I am unable to reproduce it. So I really don't know what to do.
I have updated to 4.4.1, and the problem persists. I have submitted a bug report with octave developers. https://savannah.gnu.org/bugs/index.php?54507
All, After updating to the newer qt5 ports, the problems seems to have gone away. I now have qscintilla2-qt5-2.10.4 qt5-assistant-5.11.1 qt5-buildtools-5.11.1 qt5-core-5.11.1 qt5-dbus-5.11.1 qt5-designer-5.11.1 qt5-gui-5.11.1 qt5-help-5.11.1 qt5-linguist-5.11.1 qt5-linguisttools-5.11.1 qt5-network-5.11.1 qt5-opengl-5.11.1 qt5-printsupport-5.11.1 qt5-qmake-5.11.1 qt5-qml-5.11.1 qt5-quick-5.11.1 qt5-sql-5.11.1 qt5-sqldrivers-sqlite3-5.11.1 qt5-testlib-5.11.1 qt5-uiplugin-5.11.1 qt5-uitools-5.11.1 qt5-widgets-5.11.1 qt5-x11extras-5.11.1 qt5-xml-5.11.1 qt5-xmlpatterns-5.11.1 This report can probably be closed.
Sounds good to me :) -- please feel free to re-open the issue for further investigation if it should re-occur. mfg Tobias
