Comment 3 for bug 1317976

Paul, thanks for your confirmation and for applying the patch.
If there are issues with the core dump, you could try to build Zorba with the gcc options -fsanitize=address and -fsanitize=undefined. That leads to a detailed crash report if the program terminates unexpectedly. Alternatively, valgrind could also be an option to get more information about the context of the segfault.

I currently don't have a Ubuntu machine available but it seems you can get pre-built packages of gcc 4.9.0 here:
