Description of problem: Due to Fedora 28 defaulting to `-D_GLIBCXX_ASSERTIONS`, a few (rather benigm) cases of undefined behaviour in GNU Radio's C++ code led to `aborts` (mainly, those were "getting the pointer to the second, optional, input stream, and then only using it if the block's actually configured to have two input streams"; they have since been fixed. (see CHANGELOG.md) This happened in upstream release 3.7.13.4. Following upstream is hence strongly recommended! Version-Release number of selected component (if applicable): 3.7.11-5 (F28/F27) to 3.7.13.3 (F28 updates/rawhide) How reproducible: reliably Steps to Reproduce: 1. Generate flow graph with float_to_vector, but only one input. 2. Run Actual results: Abort Expected results: Normal operation Additional info:
