Lifetime error?

[GuillaumeGomez]

Hi,

I have the following file. If the line 131 is set at line 152, so just above this line:

let mut s = rgsl::MultiFitFdfSolver::new(&T, n as u64, p as u64).unwrap();

I get the following error:

examples/multifit_solver/main.rs:152:47: 152:48 error: `T` does not live long enough
examples/multifit_solver/main.rs:152     let mut s = rgsl::MultiFitFdfSolver::new(&T, n as u64, p as u64).unwrap();

error: aborting due to previous error

Is that normal? The variable does live long enough so I don't get why there is an error in here.

Triage: the original file is gone. @GuillaumeGomez if you're still seeing this, can you give me a new reproduction? Closing till then.
