roundoff error prevents tolerance

[Patrick Dupre]

Hello,

Using 
status = gsl_integration_qag with
 abs_err: 1e-07 rel_err: 1e-07, size: 200, key: 1

I get
gsl: qag.c:247: ERROR: roundoff error prevents tolerance from being achieved
Default GSL error handler invoked.

The bizarre thing is that the code fails without returning the status.

In addition, I cannot find documentation about this error

Thank
