Dear ALPS,

thank you for existing!

I found something that looks like a bug. I use the worm algorithm (Windows XP) with the following parameter file. When I run the code, it exits without giving any detail. If I change the letter W with any other letter it works.



 LATTICE="square lattice";
 L=4;
 MODEL_LIBRARY="pairedBEC.model.xml"
 MODEL="boson Hubbard";
 NONLOCAL=0;
 V    = 1.0;
 W    = 0.1;
 mu   = 0.5;
 Nmax = 2;
 T = 0.1;
 SWEEPS=500000;
 THERMALIZATION=10000;
 { t=0.01; }
