Hi, On which env and version are you? 2 things: 1) bt you can try to retrieve a backtrace by using "ulimit -c unlimited" and relaunch "make" or type "make CppunitTest_toolkit CPPUNITTRACE="gdb --args" then in gdb, just type "run" then "bt" to retrieve bt. If 1) gives nothing-> 2) build tools (at least on Linux since I don't know for the rest) Perhaps some build tools have upgraded on your machine (eg gcc) and some cache is wrong So I'll try this: "ccache -C" (to clean ccache) make clean (to remove any built part) ./g pull -r ./autogen.sh && make Hope it helps a bit Julien -- Sent from: http://document-foundation-mail-archive.969070.n3.nabble.com/Dev-f1639786.html
