I'm working on GSL+callbacks, and have hit a genuine Heisenbug - the behavior changes depending on when/where I break and/or step over or into code. Callbacks are getting hit successfully(!!!)
but there is one function that crashes, unless I step over the call, in which case I get an error.
In particular, if I step far enough into things to see the call, calling gsl_multifit_fdfsolver_set() is raising an error (vs. crashing if I don't look<g>) that says 'No module to load address from'. Anybody know what that means? I'm using the CogVM on Ubuntu
Lucid.
That's the error associated with FFIErrorNoModule, see ExternalFunction class>initializeErrorMessages. An FFI call will fail with this when it can't find the call address in the first method literal (or when doing ExternalFunction>invokeWithArguments
and the receiver doesn't have a call address).
