I have access to one, but on a setup running 1.16.x, cannot upgrade to git master there. I'll try with some other new QMI device. > Bu can't I just run valgrind on the MIPS CPU?

If we're interested in finding invalid read/writes in memory (ignoring leaks), the valgrind call would be basically this: # G_SLICE=always-malloc valgrind --log-file=valgrind.log /usr/sbin/ModemManager --debug The valgrind.log file would contain the errors reported. -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
