uBLAS uses standard C++ exceptions to report such errors.

Are you sure that neither BOOST_NO_EXCEPTIONS nor
BOOST_UBLAS_NO_EXCEPTIONS is defined?
According to exception.hpp any internal_error and external_error aborts
the program with a
// the type of *this is the exception class that inherits from
// std::runtime_error or similar classes.
Are you able to enable core dumps? (command "ulimit -c" on unix)
