There's no simple fix. The log system needs to have a buffer of some 
size when calling vsnprintf(). (Used for parsing variable number of 
arguments for dolfin::message().)

If the matrix is big, just print it to file and then look at it:

File file("matrix.m");
file << A;

or

File file("matrix.xml");
file << A;
