Package: qtcreator
Version: 16.0.1-2
Hi,
I'm using QtCreator on Debian-13 to debug a custom LibreOffice build.
(quite big build with debug symbols)
It's much more convenient for me, to start the LibreOffice process
myself. So I use this command to attach QtCreator to it:
qtcreator -client -debug $(pidof -s soffice.bin)
This works fine for the first time after starting QtCreator. In the
simplest scenario I then hit "continue" in the QtCreator debugger an
then close LibreOffice.
If I then repeat this, by starting LibreOffice again and running
qtcreator with "-debug ..." for a second time, QtCreator hits a
segmentation fault.
I tried debugging QtCreator itself using GDB.
cd libreoffice.git/
./autogen.sh --enable-dbgutil
make
make qtcreator-ide-integration
gdb -ex=r --args qtcreator libreoffice.git/lo.pro
Thread 1 "qtcreator" received signal SIGSEGV, Segmentation fault.
