I'm just curious then what 

CGAL::Interval_nt<false>::Test_runtime_rounding_modes::Test_runtime_rounding_modes

is doing.

I followed your advice and recompile it in debug mode, this time it prompted
me for input files and seem to actually perform the boolean operation, but
it crashed again (@array.h).
Here is the output of 'where' in gdb:
