--- Begin Message ---Package: libqt5qml5 Version: 5.10.1-3 Hi, during package build of, for example, qtwebsockets-opensource-src (5.10.1-2) its testsuite gets a segfault. I can get a backtrace; unfortunately, most values for inspection are optimised out though: (gdb) bt #0 0xf7f96035 in ?? () #1 0x02290450 in ??
