Hi,
I try to build LibreOffice 4.4 and master on Ubuntu 14.10 x86-64 using
clang (version 3.5.0) instead of gcc (version 4.9).
I get two unit-test fails by segmentation fault:
CppunitTest_basic_enable
CppunitTest_basic_nested_struct
It worked with gcc, so I guess the errors are related to the use of
clang. Is there something I can do from my side?
please (turn on --enable-debug or --enable-dbgutil if you haven't
already and) run the tests in a debugger with:
CPPUNITTRACE=gdb --args make CppunitTest_basic_enable
and when it crashes use bt to get a backtrace and post it here.
I first did a complete rebuild with --enable-debug turned on and all
went fine, no crash.
Then I did a complete rebuild with --enable-debug turned off and it
failed CppunitTest_basic_enable with segmentation fault.
So I turned on --enable-debug again, set export CPPUNITTRACE=gdb
--args and did only make CppunitTest_basic_enable
