<div dir="ltr">Hi, Im trying to run the llvm/clang static source code analyzer on libreoffice ~master, but ran into some unit test failures. I told 'scan-build' to use the clang/clang++ compilers instead of gcc. I ran the suggested 'make testname DEBUGCPPUNIT=TRUE' commands in order to get the backtraces of 'CppunitTest_sc_rangelst_test' [1], 'CppunitTest_sc_filters_test'[2], and 'CppunitTest_sc_ucalc'[3]. Im running Fedora 23. Any and all suggestions about what's going on and/or how to go about troubleshooting things are more than welcome. - Maarten [1] scan-build: Using '/usr/local/bin/clang-3.8' for static analysis make -j 8 -rs -f /home/maarten/src/libreoffice/core/Makefile.gbuild CppunitTest_sc_rangelst_test [build CUT] sc_rangelst_test Catchpoint 1 (throw) Catchpoint 2 (catch) [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1".
