Ladies and Gentlemen,

I'm having a bit of a difficulty with something probably very very simple: I'm writing a simple MC code, which I just derive from the Ising scheduler example of ALPS 1.3.5. The problem appears once I try using the evaluate.C code from the same example. Even if I just take the code from an example, it throws a bad lexical cast exception. Looks like I can nail it down to a line, but the line itself is a bit of alea magic and I simply have no clue how to fix it.

Hoping that somebody would spend a minute of their time and have a look at it, I'm attaching a minimal example which shows this behaviour. Here I just copy the sources from the scheduler example directory and only patch the source of evaluate.C. Below is the listing of what I'm doing.

Any suggestions would be kindly appreciated,

Zhenya
