    The GSL routines are C: It is impossible for error handlers  
called by C
routines to throw an exception, since throwing an exception across a  
C routine
will cause the program to be unconditionally terminated by the C++  
exception handling system.
This can only be fixed by recompiling the library source itself with  
a C++ compiler.
