Adding (hopefully not just noise) to this thread, I am curious as to whether my stopping flow graphs that contain a QT GUI time sink or frequency sink resulting in a segmentation fault is related to gr built with 8.2.1 while opensuse Leap 15.2 system libraries were built with GNU C++14 (SUSE Linux) version 7.5.0. This fault does NOT occur with the QT GUI sink and otherwise, everything seems to work. Note that the CMakeOutput log contains: warning: MPFR header version 4.0.1 differs from library version 4.0.2-p6. No action requested but comments are invited.
