[Help-gsl] Can I use an error handler that throws exceptions?

[Jordi Gutierrez Hermoso]

I wrote my error handler that throws exceptions instead of printing
error messages and calling abort(). I attach the relevant code in case
anyone wants to analyse it.

At any rate, my error handler does indeed throw exceptions, but is
there something I am not understanding about C/C++ or the GSL? I ask
because e.g. in the following code:

#include <iostream>
#include "error.h"

int main(int argc, char** argv){
 using namespace std;

 gsl_set_error_handler(&error_handling::errorHandler);

 gsl_vector* thing = gsl_vector_alloc(10);

 try{
   gsl_vector_ptr(thing, 100);
 }catch(...){
   cout << "Exceptions work!" << endl; //Never gets here.
   abort();
 }
}

the exception isn't caught, and I end up with something that is worse
than the default GSL error handler, namely, also terminates abruptly
and gives even less information than the default. :-(

Why aren't my exceptions unwound back up to the code that throws them?

Thanks again,
