Hello Nils Jarle Haugen, these instructions are great to reproduce the crash.
Below is the backtrace with debug symbols installed. It looks like the vector m_boardLed->m_pin contains invalid data, and therefore we crash when calling methods on an element retrieved from it. Valgrind shows the same backtrace, while the accessed element got free'd before. This should probably be forwarded to upstream developers. Upstream commit [1] might be related, but does not apply cleanly to 0.1.7+dfsg-2. Kind regards, Bernhard [1] https://sourceforge.net/p/simulide/svnrepo/434/ Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00005588dcda66e5 in Arduino::initialize (this=0x5588de934280) at ../src/gui/circuitwidget/components/mcu/arduino.cpp:173 173 m_boardLed->getEpin(0)->setEnode(enod);
